Plex Media Server Logs_2025-11-01_21-02-36.zip (5.2 MB)
When I use the “Plex Media Server” icon in the DSM, I get directed to a login widow from Plex (screen shot attached), confirming my email address and asking me to sign in. When I click “Sign In,” I’m instantly sent to a dead end (screen shot also attached): Safari telling me that there is a problem with my request being for an http rather than an https address
And the dead end is this:
This result happens with my brand new MacBookAir which I deployed with a “clean install,” thus not copying any of the old settings. It is running MacOS 26 Tahoe — 26.0.1
My old iMac and my old MacBookAir still function properly (i.e., clicking the PLEX icon in DSM launches PLEX normally) and I have tried to search for any settings that may be wrong. I’m obviously missing something here….
I am hoping for troubleshooting suggestions so that I can launch PLEX out of Synology DSM using my new computer.
Server Version#: DSM 7.1.1-42962 Update 9
Player Version#: 1.42.2.10156-700010156
<If providing server logs please do NOT turn on verbose logging, only debug logging should be enabled>
Somewhere you have it set for HTTPS initially.
When you click the link, (look at the error message), it’s trying to go HTTP and Safari is saying NO because DSM is trying to redirect (305)
I suspect you have the setting on DSM to force HTTPS ?
To circumvent this, use a different browser , get to the DSM desktop, and make the settings changes.
Couldn’t it be a Safari policy which forces all connections to the https protocol?
If it is (I wouldn’t know since I’m not using Safari), then there should be a way in the Safari preferences to disable it for the IP address of the NAS.
At ChuckPa’s suggestion, I deselected the box in DSM Control Panel>Login Portal, the one which says: “automatically redirect HTTP connection to HTTPS for DSM desktop” Deselecting that did not resolve the problem.
Also at ChuckPa’s suggestion, I tried a different browser. It works like a charm with Firefox. But with Safari, it still behaves as if launching Plex from Synology desktop is sending a request for HTTP (and not HTTPS).
I double checked to be sure that my home login to my Synology server (with both Firefox and with Safari) is https://
It’s as if the Plex “Package” in DSM is sending out a HTTP request using Safari on my new computer, but that it’s sending out the regular HTTPS request on Firefox on the same machine.
I think I’ve followed all ChuckPa’s suggestions, but to no avail. Thank you in advance for any additional suggestions to try.
It looks like Apple’s MacOS Tahoe has automatic redirection from HTTP to HTTPS, and that the settings are not easy to over-ride. It seems that Plex is interpreting the logon request to be HTTP when it emanates from my new computer using Safari (but not when using Firefox). It almost looks like Plex is seeing something different depending upon which browser the request comes from(??). I’m still in the dark over here. Thx
