Server Version# PlexMediaServer-1.18.6.2368-97add474d-x86_64
Player Version# 4.22.1
My Plex web app (https://app.plex.tv/desktop#), in both Firefox and Chrome browsers, works as expected with the critical exception that my (Synology DS718) Plex server is “currently unavailable.”
In Windows Explorer, I can access my Plex share on my Synology NAS, as well as my mapped network drives containing Movie and Music folders.
I have restarted my modem/router, and it continues to work properly. I have tried to perform troubleshooting tips, but to no avail.
During a couple of days in which I did not use my NAS or the Plex app (which until then had been working fine), I installed, and then subsequently uninstalled the Kaspersky suite of programs. Now when I try to use my NAS and Plex, the issues described above are present.
When I click on the Plex Media Server icon in Synology’s DSM (http://10.141.59.20:32400/web), so doing returns the error message page: “This site can’t be reached.” I’m thinking that perhaps something has gone wrong in Firewall or anti-virus settings in Windows 10.
I should add that Synology’s Video Station app plays my (Synology-stored) movies properly.
I have saved my Logs zip file of Plex Media Server. Thank you. (upload://zhpX5PTze5aUdWyxS9TUUsxpvFO.zip) (3.2 MB).
I don’t think this a problem with your Windows or Anti-virus. I’ve had the same problem with the latest plex server version 1.18.6.2368. My plex server had stopped randomly, I’m assuming due to a bug. You can fix this by going to your DSM -> package manager -> Installed and check if your Plex Server is running.
Lets hope the plex team fixes the random shutdown bugs soon, seems a ton of people are having this problem.
And, indeed, my Plex Server, every time I check it, is shown as “running,” as per DSM -> package manager -> Installed.
But, “When I click on the Plex Media Server icon in Synology’s DSM (http://10.141.59.20:32400/web), I receive an error message page which reads: ‘This site can’t be reached.’” Similarly, when I load the web app (https://app.plex.tv/desktop#), I receive the message that my (Synology-based) server is “currently unavailable”:
“DSM” stands for (Synology’s) DiskStation Manager, which is the web-based operating system for every Synology NAS.
Here is how to connect to DSM:
Once DSM is loaded in your web browser, you do the steps:
Package Center → Installed → Plex. This is shorthand for: (1) click on Package Center; (2) click on Installed; (3) click on Plex Media Server; then take note whether it is running:
And, even when I run my Windows 10 Plex Media Server (as opposed to my Synology Plex Media Server), I similarly receive a message that “Plex is not reachable”:
The steps I listed are simply to determine whether Plex Media Server is running on one’s Synology DiskStation Manager. Implementing them will have no affect on the security of your movie library. But whatever you do–somehow–make a full backup of your movie library; and, continue to do so on a regular basis. This is especially important when one is just getting started with Plex, but is essential at all times for all users, even the most advanced.
I’m willing to help further if I can with questions you may have, but since your questions are off-topic to this thread, please make a new post of your own for this purpose, titling it based on whatever your question may be.
I can confirm that on 918+ I had this issue since 2 PMS updates ago. More precisely, since version 1.18.4. In other words, the PMS on my 918+ goes AWOL with the following 2 packages, even though the DMS reports the PMS service as running:
As a result, I have uninstalled PMS using the Package Center (I have not touched anything else such as shares, files or user accounts) and installed version 1.18.3; more precisely: PlexMediaServer-1.18.3.2156-349e9837e-x86_64.spk.
I can confirm that over the last couple of days I’ve had no issues on 918+ compared to before when I had to restart the PMS service at least once a day.
A note that you cannot install 1.18.3 over a later version. You have to uninstall that PMS version first. Nothing was affected by this process; all libraries, art work, etc. remained untouched.
Bottom line: it seems like version 1.18.4 and 1.18.5 affect somehow Synology devices, however, not all of them. My 3615xs is fine with version 1.18.5 and the same DSM version 6.2.2 so I’m not sure what causes this weird behaviour on my 918+.
Many thanks to Rasculatul and beebware for advising me to revert to: PlexMediaServer-1.18.3.2156-349e9837e-x86_64.spk. I did, and all is now working properly. O that I might have implemented this simple solution initially.
Having same problem here, but plex server install on windows server 2019 as service. This is not just a Synology problem.
Installed Version 1.18.5.2309
Thank you @Rasculatul or the detailed post. I was struggling, like you, with 1.18.4 hoping that 1.18.5 would fix the random AWOL issues on my 918+. Rolling back to 1.18.3 stabilized my environment just as you mentioned. Kudos.
I can confirm as well, reverted back to 1.18.3 on both 713+ and 916+, and no more issues. Any version after that would crash after a day or so, and would remain unreachable until the package is restarted, even though it’s listed as “running”.
Well, another update. Since I didn’t like to have 1.18.3 version on my 918+, I have uninstalled PMS again and this time I have deleted the Plex share on Synology as well as the plex user account. After that I have installed 1.18.6 (the latest version), recreated the libraries (which, obviously, took a while to scan and populate the art work) and so far it has been running fine for 2 days. I am wondering if it had something to do with the caching information in the Plex share.
I will provide another update in a couple of days on the stability of PMS.
Using a 218+ here. The newest update did not work on it either. What is the procedure for rolling back? Just manually update via DSM with the older version?
