Original Pull Request: https://github.com/netbirdio/netbird/pull/4000

State: closed
Merged: No

The regex blocked labels that are allowed by rfc1035 like "x", "x1", "x--x" and possibly some more.

The regex check was also redundant because it is directly followed by dns.IsDomainName(domain)

Describe your changes

I only removed the regex check from validateDomain().

This change still requires an update to management/server/nameserver_test.go because it tests for the too strict domain validation.
