Permission denied with local runner

Hello everybody,

I have been using an already installed GitLab via Intellij on my own server for several months.
Everything went perfectly. After an update of the server operating system, however, the runner doesnt worked and I had to install a local runner.
This now runs as a docker. However, the deployment no longer works. GitLab reports:

Unfortunately I don’t know what to do to make it work.
Does anyone have a hint to solve this problem?

Thanks in advance,
