[Error] - Unable to launch any session - Kasm 1.16.0

[nngne]

Hi, On August 27, 2025, kasm was working correctly, but that day after 2 PM, the server's disk space filled to 100%; one of the containers in /overlay2 had 39GB - which I deleted. This was a user session that didn't close after the declared 20-minute period – declared in groups. The next day, August 28, it was difficult to log in because we received a "Login Failed" message, despite the correct password and login. After some time, we managed to log in, but attempting to open the session results in an error message. I upgraded to 1.17, but it didn't help. I restored a snapshot of the server, and it's currently on version 1.16. I noticed that the kasm_sidecar_network container isn't starting. Please help.
