Browser shows loading spinner only

sometimes my Dashboard works and then it stops and the browser is only showing a loading spinner.
When I look into the network tab I can see the document is loaded halfway, stopping at
<div class="tooltip">Pi-hole is a Linux network-level advertisement and internet tracker blocking application which acts as a D
and fontawesome.js shows pending.

I've updated everything(?) and can't find any interesting info in any logfile. Maybe you can hint me where to look?

I'm running heimdall in a proxmox environment, installed with https://github.com/tteck/Proxmox/raw/main/ct/heimdall-dashboard.sh

Nevermind: Tailscale Subnet routing was the issue. But weird, that all other machines run without issues, only Heimdall was problematic.
