It is said elsewhere that server url must not be a suffix of the base_domain. To me, server is a suffix of base here -- yes, additionally they are equal. Perhaps the wording using "suffix" needs to be adjusted?

you are write, it should probably be reformulated since we allow different domains, open to proposals.

See updated error message. I think the new one is more intuitive, see if you like it better

Currently users upgrading from 24.05 to 24.11 may stumble across an overly-restrictive BaseURL and ServerURL check in headscale[1]. A fix has been merged upstream[2], this is backport, so users can have it easier upgrading from 24.05 to 24.11. [1]: juanfont/headscale#2210 [2]: juanfont/headscale#2248
