Can´t login after clean install

[Sentinel-sys]

I have just made a completely new installation of KASM for the second time and the installation seems to go through without any problems. Unfortunately, I can neither log in as admin nor as user.

During the first installation I noticed that the capacity of my Ubuntu volume group was halved. From 50 GB to 25 GB.

During the second installation I did not use LVM and gave the VM 100GB as a precaution. Unfortunately the error remains.

Operating system: Ubuntu Server 24.04 with all updates

sudo docker ps shows:

It seems "kasm_rdp_https_gateway" is constantly restarting.

sudo docker logs -f --tail 10 kasm_api shows:

What did I do wrong?

I have also experienced this issue. I have tried clean installs of both Debian 12.6 and ubuntu 24.04. Both installs successfully complete without errors. kasm_rdp_https_gateway constantly restarts and prevents login.

I have many difficulties with the kasm guac container which frequently goes into the unheathly state which prohibits any connection to the service. This often occurs in correlation with heavy system load. See issues number #571 #638. The only way out for me is to completely reinstall kasm on a lightly loaded system. This led me to create a procedure to uninstall/install Kasm and automatically create a workspace. See issue number #476

I have now got it to work. However, not under Ubuntu but Debian 12. I also noticed that I had the same error at the beginning. After about half an hour the container “kasm_rdp_https_gateway” did not restart.
