Reverting to image: ghcr.io/ifargle/headscale-webui:v0.6.1 fixes the issue.

Currently working on it! We had a major rewrite. I should have done more testing. I'll push to v0.7.1 when complete

[iFargle]

I've rolled back 0.7.1. Latest is now 0.6.1 -- A fresh image will be available in about an hour.
