Start with the error message
- Unknown or expired
- Ask a server admin for a new invite.
- Invalid invite
- Copy the whole link and keep the code’s capitalization. Invite codes are case-sensitive.
- Too many servers
- The usual limit is 100 servers, or 200 with Nitro. Leave enough servers to get below your current limit.
- Banned from the server
- Ask a server admin to review the ban. A fresh invite does not remove it.

If you manage the server
- Open Server Settings → Invites. Check that invites are not paused and the link still exists.
- Create a replacement invite. Review expiration and maximum uses. Non-expiring invites are available for Community servers.
- For Boost delivery, check join settings and security bots before submitting the replacement.

Custom invite still fails?
For a custom discord.gg/yourname link, also check that the server still has the perk and at least one text channel visible to @everyone.
Still cannot join?
Send the server admin the exact error text and ask them to test a fresh invite. For a Yaman Boost order, send support the replacement link with your existing order ID.
