I am trying to install a simple job in Gitlab-CI. It should just copy most of the files (.php) in the repository to a different folder (from repository to Apache's /var/www/html/...).
The output goes like this:
Using Shell executor...
Preparing environment
Running on my.server...
Getting source from Git repository
Fetching changes with git depth set to 50...
Reinitialisierte existierendes Git-Projektarchiv in /home/gitlab-runner/builds/TyGXtawE/0/sdp-dev/ibo-php/.git/
fatal: unable to access 'https://gitlab-ci-token:[MASKED]@gitlab.sustainable-data-platform.org/sdp-dev/ibo-php.git/':
The requested URL returned error: 500
So I can find the corresponding problem in /var/log/gitlab/gitlab-rails/production.log

# ... stacktrace
I have installed the runner from "https://gitlab-runner-downloads.s3.amazonaws.com/latest/rpm/gitlab-runner_amd64.rpm" and gave it the token from Gitlab's GUI.
Gitlab (v 14.5.2) and the runner (v 14.10.0) are running on the same machine.
All this might be overhead for some cp -r, but I would like to understand the error for upcoming more complex jobs. Any idea how to debug the registration-token, how to find the problem?
Update
403 for Gitlab Runner from Gitlab?
It seems like gitlab-runner just gets a 403 (forbidden) from Gitlab. So I might need to change something in the corresponding (Apache). But how can I debug this (ERROR: Checking for jobs... forbidden)?
How to register a runner?
There is this command: sudo gitlab-runner register --url $URL --registration-token $REGISTRATION_TOKEN. But when I put the right data (URL, REGISTRATION_TOKEN) in this command (not using bash variables!), I am asked for the same data again (URL, TOKEN) and I just do c/p. E.g. Type the URL [MY_URL]:, then I c/p MY_URL and hit enter. Is this OK?
token / unhealthy runner problems
No success after creating a new token in gitlab and registering a new runner, also after updating Gitlab to v14.10.
But I can see some problems in /var/log/messages.

You can see this problem elsewhere in SO, but I could not find a solution (googling etc.).
Here? https://gitlab.com/gitlab-org/gitlab-runner/-/issues/28965
Some things you might try:
Create a new token
Update Gitlab
