Web Terminal - Connection error

There is no need to add any rule to allow port 8085. What did you do? That doesn’t mean that your system must be upgraded, that means that the browser is trying to speak to the app in HTTP and the app requires WebSockets. You should use the button >_ inside Hestia to access the web terminal. To view that icon the user must have assigned a shell like bash, jailbash, etc. all but nologin.
