Why is Amazon Web Services Elastic Compute Cloud now Polling My Plex after Remote Access is enabled?

Plex Media Server Remote Access

2 Questions…

  1. After enabling Remote Access to my Plex Server, Amazon Web Services, Elastic Compute Cloud, EC2, EU ( specifically 46.51.207.89 and 54.170.120.91) are now polling my Plex remote access ports…why?

  1. If this is Plex.tv confirming the accessibility of my servers then fine, but is there a full list of these IP Addresses so I can add them to my firewall/IDS rule set? I know what countries, telco providers, wireless providers, etc… that i want my Plex Remote Access server accessible from and the Cloud Hosting Providers are not in that list.

Or should I open a Plex Ticket for this information.

Yes, that’s what it is. It’s how your server knows to give you a green check instead of a red X by Remote Access in your settings list (and whether or not to show “Fully accessible outside your network”).

Check the “IPs Being Blocked” in the Common Problems in this doc.

Specifically, there’s an automatically updated list of IPs which might try to connect to your server for this purpose. I’ll leave it here as well…

https://s3-eu-west-1.amazonaws.com/plex-sidekiq-servers-list/sidekiqIPs.txt

As of right now, the two IPs you listed are on it.

There’s no such thing, at least not in the context of technical support.
