Media Server Shutting Down Internet

Server Version#:1.29.2.6364

Whenever I download Plex Media Server it shuts down my internet on my machine. Not the whole network, just the machine I download it on. I’ve tried this with my desktop (Windows 11) and my laptop (Windows 10) and the same thing keeps happening. Once I uninstall the media server, my internet starts working again. Is there some kind of plex setting that can fix this? Is it maybe on my ISP’s end? A windows setting perhaps? Any help would be greatly appreciated. Thanks!

this is the same thing that’s happening with my desk top (windows 11) as well, I downloaded the newest version of plex media server.

What ISPs do y’all have?

Century Link. I asked their support if it was something on their end but they said they didn’t see anything out of the ordinary.

What is not out of the ordinary for them may not be ordinary for most folks. It’s ordinary for Comcast to block ports Plex uses with their secure browsing software for example and they would not say a thing about it.

but we can wait to see what @Lazh02 is using. Other than that would need to look at server logs to see if it is doing something not normal.

I’m using Centurylink, this problem started a couple of weeks ago

I’m have been having the same issue. Pretty much haven’t been able to watch anything for the past 2 week b/c of this. I have Centurylink. Tried it on my brothers computer at his place using Cox and wasn’t working there either.

Need server logs after the internet goes down so we can see what the server was trying to do.

Have provided server logs and ping test logs on other thread for BigWheel. For others, I’ve been able to eliminate by both disabling Remote Access and checking the Run Scanner Tasks At Low Priority under Library. Having one or the other reduced internet downtime from 4 min to 10 sec.

How do I send you the server logs? I downloaded the zip file but I don’t know how to get that info to you without just copy/pasting all these 30+ files.

Reply to this thread, drag and drop the zip file onto the reply.

Ha ha wow can’t believe I didn’t try that. Thanks for the help!

Don’t see anything unusual in logs. Does your ISP have any built in antivirus or internet security type of thing?

Having the same problem. Deleted and reinstalled the Plex apps without any solution. ISP is CenturyLink.

CenturyLink doesn’t have any built in protection. McAfee is a optional addition to customers. I turned off all antivirus and internet protection programs on my computer and still whenever opening Plex Media Server my internet connection is terminated.

Thanks OttoKerner for your effort in providing the forum links. Disabling the Cyber Security setting in the CenturyLink router restored the use of PMS. I should have considered my recent change back to using the CenturyLink C4000XG router caused the problem. Thanks again.

Yup, that fixed it! Thanks so much for your help!

It would appear that sometime in the last 2 weeks, the ability to disable the “cyber security” function is no longer available - or they have moved the function. I had found it after you posted this, but it is now not even an option in the Advanced Settings for the C4000XG.
