Describe the problem

I see the following error in the client.log file.

2026-01-27T17:00:45+01:00 ERRO client/iface/configurer/usp.go:563: failed to parse endpoint: address 2001:aaa:bbb::ccc]:51820: too many colons in address

The code in usp.go does not work properly for IPv6 addresses as endpoints. I believe it would work, if the strings.Trim(val, "[]") is removed.

NetBird version

0.64.2
