Error messages
Every error in Kops has a title, a fact and a next step. This is where to look up the ones that are not about a purchase — sessions, invitations, uploads, tools, messages, streams and billing.
Errors about a purchase are on Attempt errors — that page covers the twelve families a buy can fail in, including the shipping and anti-bot ones. Everything else is here.
How to read one
Three parts, always in the same order:
- The title — what it is.
- The description — what happened, as a fact.
- The suggestion — what to do, when there is something to do.
No suggestion means there is nothing useful for you to do. That is a deliberate answer, not a missing one.
A title on its own is not always enough to identify an error. A few are shared between contexts — Session Expired is ours in one place and your Vinted account's in another, and two different daily ceilings both call themselves Daily Limit Reached. When two rows look alike, the description is the deciding line.
Signing in
| What you see | What to do |
|---|---|
| Invalid Credentials | Check the email and password, or reset it |
| Email Not Verified | Open the verification link in your inbox, or request a new one |
| Email Already Registered | Sign in instead, or reset the password |
| Invalid Email Format / Password Too Short | Fix the field and retry |
| Session Expired | Sign in again |
| Sign In Again On This Device | This device's credential is out of date. Your other devices are unaffected |
| Device Changed | The session was started on a different device. Sign in again here |
| Security Token Expired | Just try again |
| Verification Failed | The bot check did not pass. Reload the page and try once more |
| Reset Link Expired / Invalid Reset Link / Reset Link Already Used | Request a new password reset |
| Verification Link Expired / Invalid Verification Link | Request a new verification email |
| Already Verified | Nothing to do — your email is confirmed. Sign in |
| Invitation Required | Registration is invite-only right now. Join the waitlist |
| Sign-In Handoff Failed / Invalid Bridge Link | You arrived on a link that was meant to carry your session across. Sign in normally instead |
Passkeys
| What you see | What to do |
|---|---|
| Passkey Not Recognized | Try another passkey, or sign in with your password |
| No Passkeys Registered | Sign in with your password, then add one |
| Passkey Setup Failed / Passkey Sign-in Failed | Retry in a moment |
| Invalid Passkey Response | Try the passkey prompt again |
| Name Required | Give the passkey a name |
| Passkey Not Yours / Passkey Not Found | Refresh the list — that passkey is not on this account any more |
Once you hold a passkey, a password sign-in asks you to confirm your identity, and the email link is the way past it when you cannot. That link has errors of its own:
| What you see | What to do |
|---|---|
| Sign-In Link Expired | It lasts 10 minutes. Request another |
| Sign-In Link Already Used | Each one works once. Request another |
| Invalid Sign-In Link | Open the most recent email, not an older one |
| MFA Session Expired / Invalid MFA Session / MFA Session Already Used | Start the sign-in again from the beginning |
None of these lock you out: your password still works, and the email link is always available. See Profile and security.
Your Vinted accounts
| What you see | What to do |
|---|---|
| Session Expired | The account's Vinted session is dead. Reconnect it with fresh credentials |
| Invalid Token | Vinted rejected the tokens. Reconnect the account |
| Session Refresh Required | Log in to the account in your browser, copy the latest cookies, and retry |
| Account Banned | Vinted suspended it. Remove it and add a different one |
| Blocked at Checkout | Vinted is refusing checkout on this account. It goes to quarantine and comes back on its own |
| Connection Failed | The account's session may be invalid — try reconnecting it |
| Missing Address | The account has no geocoded address. Refresh the account |
| Vinted Session Setup Failed | The first handshake with Vinted did not complete. Retry the connection |
See Adding a Vinted account and Account states.
Teams and invitations
| What you see | What to do |
|---|---|
| No Available Seats | Buy more seats — Account packs and seats |
| Invite Already Pending | Wait for it to be accepted, or cancel it first |
| Invite Expired | Ask an admin for a new one. Links last 7 days |
| Invite Already Accepted / Invite Not Found | The link has been used, or revoked. Ask for a new one |
| Wrong Account | The invitation was sent to a different email. Sign in with that one |
| Already a Member | Nothing to do |

Filters, folders and sharing
| What you see | What to do |
|---|---|
| Filter Not Found / Folder Not Found | Refresh the page |
| Access Denied | You can only modify filters you own |
| Not Your Folder | Same, for folders |
| Preview unavailable | The preview service is briefly down. Try again in a moment |
| Too many filter requests | You have opened an unusual number of filters quickly. Slow down and try again shortly |

Uploads and photos

|---|---|
| File Too Large | Upload a smaller file |
| Invalid Upload | Check the file and try again |
| Image Processing Failed | Try a standard JPG or PNG |
| Upload Failed | Ours. Try again in a moment |
A photo is required on an item complaint, so these are the errors that stand between you and opening one. See Disputes.
The toolbox
Two layers, and they show up in different places.
A tool job that fails puts a card in the tool's own page:
| Where it went wrong | What you see |
|---|---|
| Your input | No Images, Too Many Images, Image Too Large, Invalid URL, Not a Vinted URL, Invalid PDF, File Too Large, Unsupported File Type, Invalid Format |
| Your allowance | Daily Limit Reached |
| The AI | AI Timeout, AI Busy, AI Unavailable, AI Parse Error, Content Blocked |
| The Mirror | Item Not Found, Item Removed, Too Many Requests, Access Denied, Fetch Failed |
| The Cropper | Invalid PDF, No Labels Found, Processing Failed |
| The Sales Extractor | User Not Found, Private Profile, Too Many Requests, No Sales Found, Fetch Failed |
| Ours | Server Busy, Processing Error, Storage Error, Cancelled, Unknown Error |
Everything in the last four rows is transient and gives your quota slot back — see Listing tools. Only the first two cost you a run.
Then the plumbing around a job, which you meet when a result has gone stale:
| What you see | What to do |
|---|---|
| Download Expired / Download Not Found | Re-run the tool to get a fresh link |
| Job Still Processing | Wait for it to finish |
| Job Not Found | It has already completed, or it never existed |
| Image Fetch Failed | The image could not be retrieved from Vinted. Try again shortly |
| Item Data Unavailable | Comparable data could not be loaded. Retry in a moment |
Messages and offers
| What you see | What to do |
|---|---|
| Offer Too High / Offer Too Low | Vinted bounds what an offer may be. Move it and send again |
| Offer Already Sent | Wait for the seller to respond |
| Offer Rejected | Vinted refused the offer's shape. Adjust it and retry |
| Vinted turned this down | Vinted refused the action itself, and says what it wants changed |
| Account Unavailable | The account behind this conversation cannot talk to Vinted right now |
| Message Not Found | Refresh the page |
See The buy bar.
Disputes and order actions
| What you see | What to do |
|---|---|
| Can't open a dispute | Vinted no longer accepts a complaint on that order |
| Shipment receipt required | Attach a photo of the receipt, then confirm again |
| No return address on this account | Add an address to the account, then reopen the dispute |
| Return method unavailable | Pick one of the return methods Vinted lists for this order |
| No refund offer found | Refresh — it may have been withdrawn |
| This account still syncs | You can only record your own outcome on an order whose account is gone. Wait for the next sync |
| Vinted already closed this order | Refresh to see its final status |
| This parcel is already marked delivered | Nothing to mark |
| Nothing to undo | The mark you are clearing is not there |
| Couldn't confirm receipt | Ours. Retry in a moment |
See Disputes and Order actions.
Notifications
| What you see | What to do |
|---|---|
| Discord account not linked | Connect Discord in Settings → Integrations, then try again |
| Join the Kops Discord server | You have to be in the server for a DM to be deliverable |
| Your Discord DMs are closed | In Discord: Kops server → Privacy Settings → allow direct messages, then retry |
| Test already sent | Wait a minute before sending another |
| Couldn't enable Discord notifications / Discord notifications unavailable | Ours. Retry in a moment |
| Push Update Failed / Invalid Request | Reload the app and turn the switch again |
| Unknown subscription | This browser's push registration is stale. Turn device notifications off and on again |
See Notifications.
Your profile and privacy
| What you see | What to do |
|---|---|
| Username Taken | Choose another |
| Invalid Username | Letters, numbers and _, 3–30 characters |
| Bio Too Long | Shorten it |
| Name Change Cooldown | The generated name changes once every 30 days |
| Seller Already Blocked / Seller Not Blocked | Refresh the list — it has moved on since you opened it |
| Export Failed | Your data export did not build. Retry in a moment |
| Incorrect Password | Deleting your account asks for your password. Re-enter it |
Real-time connections
Invalid Stream Ticket, Stream Ticket Required, Invalid Access Token, Access Token Required — the live connection behind the feed and the inbox lost its authorisation.
The fix is always the same: reconnect through the app, usually by reloading the page. Nothing is lost, and nothing needs configuring.
Subscription
Covered in full on Payment problems and Pausing and cancelling, but the short version:
| What you see | What it means |
|---|---|
| Payment Past Due | An invoice failed. You have 48 hours before the dashboard is walled |
| Account Over Quota | That Vinted account is beyond your plan's paid capacity |
| Seat Suspended | The workspace is over its paid seat capacity |
| Plan Limit Reached | You are at a ceiling the plan sets. Upgrade, or free something up |
| Account Restricted | An account review. Contact support if you think it is a mistake |
| Sold Out | That plan is temporarily full. Join the waitlist |
| Subscription Required / Feature Unavailable | The workspace has no plan that covers this |
| Can't pause / Pause unavailable / Invalid pause length | Pausing has conditions, and the button's tooltip names the one you are failing |
| No pause to cancel | There is no scheduled pause left to undo |
| Already Subscribed | Use change-plan rather than starting a new subscription |
When it is ours
Something Went Wrong with If this keeps happening, contact support, and a small number of others that end with Nothing to do — we have been alerted. Alongside them: Temporarily Unavailable, Service Unavailable, Invalid Configuration.
Those two phrasings mean different things. The first wants a report from you. The second is telling you the report already happened, and that retrying is the only thing left worth doing.
When it is Vinted's
Vinted Server Error, Timeout, Connection Error, Vinted Returned No Order, Parse Error, Payment Provider Error.
These are transient by nature and mostly retry themselves. If one persists across many minutes, it is an outage on their side rather than a setting on yours.
