I don't know if it's Linux issue, but when playing on Linux I was unable to launch it, Server Status was saying it's running, and localhost:8000 wasn't showing "unable to connect", but nothing loaded.

OS: Fedora Linux 36
Browser: Firefox (slightly hardened)
Kerbal telemetry Version: 2.3.0
KSP Version: 1.12.3.3173
Python Version: 3.10.6

Also I tried both installing manually and with CKAN, both had the same result.

I found #17 which fixed that one problem, but after that this mod caused different issue, so I will be making new issue.
