Seeing a lot of external connections to port 80?

LawjicLawjic Validating, Plex Pass Posts: 2 Plex Pass

I'm running my Plex Media Server from an oVirt cluster, and I noticed the host which is housing this VM had network about 70-90% utilized. When I logged into my VM, I saw a lot of connections to port 80 externally.

I stopped plexmediaserver service, and this stopped. Do we know what plex is trying to reach out to externally on port 80 for all of these addresses?

Here's an example list:

Looks like some kind of mirror connectivity/traffic - but for what? name = teewurst.cc.columbia.edu. name = mirrors.eecs.wsu.edu. name = distro.ibiblio.org. name = reflector.westga.edu. name = host-173-243-16-24.millry.net. name = reflection.cites.illinois.edu. name = mirrors.wvstateu.edu. name = 198-255-114-50.host-engine.com. name = mirrors.xmission.com.
** server can't find NXDOMAIN name = mirror.cogentco.com.
** server can't find NXDOMAIN name = mirror.steadfast.net. name = mirror.san.fastserv.com.
** server can't find NXDOMAIN name = white.web-ster.com. name = mirror.trouble-free.net. name = mirror.net.cen.ct.gov. name = mirrors.webair.com. name = mirrors.200p-sf.sonic.net. name =

Thanks for any info you may have on this!

    Are you sure that network traffic was related to plex?

    All of those mirrors (At least the ones I checked) all appear to be linux distro mirrors.

    They are Linux distro mirrors. Whoever you're sharing the host with is running a distro mirror server.

    Nothing is related to Plex. Plex doesn't use port 80

    Thank you both. Must have been ironic timing I suppose. Just so happens to be when I stopped plex services, these connections go away, but what you're saying does make sense.

    Many thanks!
