This issue often occurs when the Authorization header is removed for some reason during the request.
If you are using a webhost, try contacting their support and explaining that the Authorization header got removed when requesting your sites API.
I can also suggest updating to the latest version of the NamelessMC plugin. You can find that one here: https://ci.rkslot.nl/job/Nameless%20Plugin/
If you continue to encounter issues, it would help out if you join our official Discord. We can provide support a lot quicker and easier in there. You can join it here: https://discord.gg/nameless/
Make sure you set path to "" (nothing) in core/config.php when installing!
A few quick things to check:
- Are you using the latest namelessmc version (pr-12 at the time of writing this)
- Does your panel template support your namelessmc version?
If you continue to have issues, join the namelessmc discord server to get further support. We can help you out a lot easier in there!
Please use V2 pr12. The V1 installation is no longer supported. It displays as recommended but is genuinely discontinued. Use V2 instead.
