[1.209.024] EOS Servers disappearing in Server Browser

Observed behaviour:

Occasionally, an EOS server will disappear from the Server Browser/Favorites tab. The server is not down at this point, as it is able to be connected remotely via VRRC and players are actively playing/chatting/moving. Refreshing the browser will repopulate the list quickly, seemingly without "searching" for servers. Attempting to use Direct Connect to join the server will present the "Server not responding" pop-up. The server will randomly reappear after a certain time or when the server is manually restarted by an Admin or scheduled restart.

This is largely a new behaviour we're seeing with 1.209.X.

Expected behaviour:

EOS Servers should be present in the Server Browser when actually up and joinable.

Affected Version/s: 1.209.024 b0

Steps to Reproduce:

• None so far. This appears to be happening randomly, but further information, if found, will be added to the ticket in the comments.
• This behaviour is not client-side, if the server disappears for one player, it's not visible for any when viewing the browser.
• It is not console specific, PC players joining EOS are also affected.

Note:

This is affecting players attempting to join Keen Official Game Servers, causing many players to be frustrated enough to stop playing.
