Request failed with status code 401 Error: Token invalid

[Nordlicht-13]

Describe the problem

I set up Netbird Self-Hosted on a vServer followed the Self-hosting quickstart guide (5 min) Already set up a user and logged in into Zitadel and Netbird with this user.

Made a manually backup like shown here: https://docs.netbird.io/selfhosted/selfhosted-quickstart#backup

After that I cant start Netbird any more.
I just get a black page with the netbird-loading-image and a message at the top
popping up all the time:

Request failed with status code 401

Are you using NetBird Cloud?

Self-host NetBird’s control plane.

I am assuming you shut off the management interface before backing up, right? If not, try to restart everything by doing docker compose up -d --force-recreate in the installation folder. (Wherever you ran the script)

[Nordlicht-13]

I did it like in the docs with

docker compose stop management
docker compose cp -a management:/var/lib/netbird/ backup/
docker compose start management

Copy and paste it to the terminal. Is it possible that the cp started before the management container was down?

Already tried to force a recreate with no luck.

Set it up new from the scratch, because it was a fresh setup.
Now it works again and I will set up my clients, groups and rules.
