Plex.tv blocking my IP/ISP?

I am trying to download the latest version of plex from plex.tv via my server, but I am not able to even connect to plex.tv on port 443 from my server.

I am able to access my plex server and content via app.plex.tv however, I can’t access plex.tv from the same server. Any idea what the problem may be? For not, I can download updates offline and then copy them to my server, but I would prefer to be able to download them directly.

Some additional info:

$ telnet plex.tv 443
Trying 52.208.253.79…
telnet: connect to address 52.208.253.79: Connection timed out
Trying 52.208.108.2…

Try again please. Cox appears to have had an outage.

Please report back
