machinaris: Internal Server Error / Webui going down

Describe the bug Webserver started to go down quite frequently. When opening webui I would get:

Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

Logs seem to show everything is still up, at least I think. Not errors except permission stuff. The permission stuff is because I open up my entire config folder for all Docker containers for easy editing. Is it going down because of this permission issue or are these just soft warnings from Chia itself?

today at 8:06:48 AM One or more SSL files were found with permission issues.
today at 8:06:48 AM Run `chia init --fix-ssl-permissions` to fix issues.

To Reproduce

Steps to reproduce the behavior, e.g.:

1. Start Machinaris
2. Leave it running for a period of time
3. Eventually webui goes down

Expected behavior Webui to not crash 😛 Or maybe re-start/notify in logs if it does.

System setup:

• OS: Debian 10 (buster)
• Docker version number (output of docker info): Docker version 20.10.8, build 3967b7d (btw command docker -v gives this output quicker/easier to find)
• Machinaris branch: main
• Machinaris version number (see bottom of every Machinaris page): Machinaris 0.5.4
