Hi!
could you post the output of the syslog?

You already showed the tasklog in the first post.

could you post the output of the syslog?

The syslog can be viewed with journalctl but you'll have to scroll with the arrow key to around the time of the problem to see if there are helpful error messages.

could someone help out please?

Maybe you can get more information by obtaining the debug log for the container start: https://pve.proxmox.com/wiki/Linux_Container#_obtaining_debugging_logs ?

hello,

im new to proxmox where do i input journalctl?

The Proxmox host console or shell or via SSH. It's a Linux command line program.
