Error install nextcloud-client

Hello. Long worked on different versions until Nextcloud 16.0.5 on Linux.
Now when i install nextcloud-client gives an error
“Access denied your token is invalid or expired”

Hey there,

I have the exact same issue. Running server 16.0.5 as well as the clients (latest AppImage 2.6.0) I want to connect (currently 2) on linux. According to nginx the first few processes the client goes through when setting up the connection seem to be fine but at a certain point I get a 404 response. Nextcloud log does not show anything about it and I can access the cloud via browser and Android sync agents.

Log in nginx looks like this:

Thanks for looking into this

And now what?
