Live viewer not updating (Fabric 1.19.2 1.10.37)

[SeaCrusher27]

When I run /spark profiler open, the link for a live viewer is generated, but when I look at the live viewer the statistics are not refreshing. The latency seems to update periodically but the rest of the page does not seem to load.

Im running this on a home server so is there a port that I haven't forwarded or a setting i have missed?

I am facing this issue too. My router & provider can't open ports for no reason, and now stuck with ngrok, which doesn't open ports (I am using git-Paper-318 (MC: 1.20.2) (Implementing API version 1.20.2-R0.1-SNAPSHOT) (Git: 9271ee7)
