Can't claim server

Plex Media Server
1

I have a really strange problem trying to claim a server, I’m not sure if it’s a Plex problem or something else. Anyway, the problem is that I’m unable to visit plex.tv on the system. If I force https, then I get a connection error due to a problem with HSTS, if disable HSTS and just try to visit plex.tv I end up at a login screen for “oceanicweather.com” and I have absolutely no idea what might be causing that. If I use nslookup to resolve plex.tv I get the following IP addresses:

Non-authoritative answer:
Name: plex.tv
Addresses: 52.49.59.29
52.16.11.44
54.220.32.65
54.170.183.27

If I do the same lookup on a different system I get:

Non-authoritative answer:
Name: plex.tv
Addresses: 54.220.32.65
52.49.59.29
54.170.183.27
52.16.11.44

Both systems are using Google public DNS servers for lookup.

Check for any Plex-related entries in your hosts file.
Check for intrusion detection systems (or anti virus suites) which decrypt secure traffic and re-encrypt it with their own “intermediate” certificate.

Thanks, should have thought of checking the hosts file, must have hardcoded an entry sometime in the past.
