Hello! I am currently running into an issue where every time I start my plex server the internet in my computer stops working. I tested by trying to go to google.com for example and I get ‘this site cant be reached’ error.
If I select the open plex option from the menu, plex takes a while until the user select screen appears, sometimes it does not load at all. After I get the select user screen. it takes a long time to load after I enter my credentials. The majority of the time I get plex is not available and other times when I am able to log in, the plex media sources are unavailable, and I am unable to load any images for my shows.
After I close the plex media server app, I wait about 5 minutes and the internet comes back!
Has anybody run into this or have any ideas about what I can do? I did a basic Plex setup, I did not add any custom tools or anything, just a right-of-the-box install.
Server v 1.29.2.6364
OS Win 11
PC: I7-12700K, 32GB RAM, RTX3080
I have the exact same thing - Every hour for about 4 min, Plex Server triggers a loss of internet access - doesn’t impact local network connectivity at all (I can ping other systems on my network and browse Gateway settings during the 4 min internet outage). I’ve been running a ping to Google.com continuously and finally tracked it down to Plex Server being the offending process. Hoping it is a setting of some sort, otherwise, I’d have to keep Plex server shut down during any time I need to have internet access.
Something we are looking into. had another topic related to the same thing. Is it possible to see your server logs after the internet goes down. Possibly it is doing something that is saturating the connection
I have been able to reduce (to about 10 sec) or eliminate occurrence by both disabling remote access and check the run scanning tasks as low priority under library. I’ve tried to isolate one or the other, but only doing both appears to eliminate it - having one or the other appeared to reduce it from 4 min internet down time to 10 sec internet downtime.
I’ve attached my ping log file along with the Plex Media logs I pulled the last couple days.
From a troubleshooting steps I had Plex running normally 12/12 and at 17:06, 18:06, 19:06, 20:06, 21:06 you can see a 4min downtime.
I turned off remote access and checked scanning at low priority around 22:05 on 12/12 and had no significant down time until I unchecked low priority scanning on 12/13 at around 10:00. At 10:06 I have about 10 sec downtime starting at :06 after every hour.
At around 12/13 at 15:45, I turned remote access on and recheck low priority scanning and 10 sec down time persists every hour.
This is not network downtime, but strictly internet downtime - I can still ping local systems at home without issue.
BTW ISP is Quantum Fiber (now Brightspeed) running a gigabit connection.
Quick update @BigWheel - after rebooting today even with the remote access disabled and low priority scanning checked - I started losing internet for 4 min stretch again which persisted even after I closed out Plex Server - I then also shut down the Plex Update Services in task manager and have had stable connection since.
No A/V on ISP - typical firewall on gateway. Of the six systems running on the network, only the one running Plex Server is having the issue and only when Plex Server is running. Only A/V I’m running is MS Defender.
I’ve had remote access disable as it did appear to make a difference to do so at one point - but after reboot, it was causing outages again even with it disabled. So I’ve had PMS shut down. I just restarted it to check the settings and as soon as it launched, my internet went out for 4 min. On the settings, the internet upload speed is set to 900Mbps (but I only recently changed that to see if it made any difference having it more accurate to my bandwidth - it was previously much lower).
According to this BrightSpeed does have a “CyberSecurity” which seems very similar to what was mentioned and what fixed the issue for others in other topic.
I saw that and tested it and it does seem to correct the problem - however, I’m concerned with the security hole it may leave to disable it. Haven’t found a way to whitelist PMS yet.
afaict it is a black list of domains that the ISP has decided are bad. You likely need to contact your ISP to ask how to edit or whitelist. You can use something like OpenDNS which has a level of customization https://www.opendns.com/
Hello, I apologize for the delay. I am still encountering the issue on my end. I am unable to log in to my plex server since the computer does not have internet access. I keep getting a ‘Plex is not reachable’ error. Is there a different way to get logs?
My ISP is Verizon, however, I do not have remote access enabled. Does this matter?
Hi @BigWheel thank you very much for this information. That was the issue! I turned off Home Network Protection and that worked! I appreciate your quick response.
