hi Guys
I have successfully run Zammad with Traefik in Docker.
After a few small mistakes I was able to solve them.
Most recently I had successfully logged on to 3 computers and was able to work well.
Yesterday I wanted to activate an additional agent and changed his password (user had been created for a long time) and logged out and wanted to log in as a test agent.
Only get the error message “Error ID” and no login possible.
Even as “admin” I can no longer log in.
What could you do? Nothing is logged in the logs under / var / log / ngnix.
I also had the ES read in again.
Still no improvement
I think the Error ID is related to the CSRF.
What can I do to get this under control?

Please check your production.log to find out what the error really is about. Let’s not fish in the dark. 🙂
`grep "Error ID xyz" /var/log/zammad/production.log`
Please also note that while some users do use Traefik, we do not officially support it and thus cannot help you in a sufficient way. Other community users might be able to help you though.

I would like to give it to you. But neither in the volume of the DockerContainer Zammad-Data nor anywhere else can I find a Production.log file.
Otherwise I would give it to you already!
I use the Docker Compose directly from you.
I have now found the logs via Portainer

@csaeum Would you mind sharing your Traefik configuration ?

Now I get everything displayed well and when I log in for the first time everything works. After an initial logout, I can no longer log in. He then always reports “csrf token validation failed”
