gaps: Error! Could not connect to Plex

Hi,

Having an issue, local install on Ubuntu as well as my docker setup. (I did Ubuntu install to rule out my docker network setup)

I input all the correct information and correct Plex token yet it still fails to connect. My Plex does require HTTPS and doesn’t allow http, however, in the spirit of trying to fix it myself, I turned this off and it still fails to connect.

Please see below error log:

Interesting, Jason is there any eta to support Required connections? I rather not turn it off, however saying that. I did turn it off for testing and it didn’t resolve the issue either.

As for the reverse proxy, I do have this and I am using sub-directories as opposed to sub domains like you are. I will investigate this more.

Perhaps it’s time to just scrap Gaps as is, and create “Gapsarr!” lol

Since all that connection code is already baked into the *arrs, just fork one of them, rip out all irrelevant code, and make the app do what Gaps does. 😉

@g4m3r7ag like I mentioned in the other GH issue, Radarr, Sonarr, Tautulli, Overseerr all support connecting to Plex via SSL. Do you use any of those apps? Have you had issues getting those to use Plex via SSL? Have you looked at the code required in those apps to support this feature? Here’s Sonarr for example…

https://github.com/Sonarr/Sonarr/blob/ec62884649f7af5f0a29346741754590e6de99ce/src/NzbDrone.Core/Notifications/Plex/Server/PlexServerProxy.cs#L153

All Gaps needs to do is to reach out to the Plex API over SSL, which is exactly the issue here. Gaps hardcodes http in the code. This is not rocket appliances, but hopefully will be all water under the fridge soon.

onedr0p on Mar 7, 2022

@onedr0p The fact that you think it requires 10 lines of code shows you don’t understand what is going on here. To add a checkbox/radio button to the UI to tell it to use SSL, sure 10 lines. All the backend work for that to actually work and access a https connection while ignoring the Connection is not private error caused by NET::ERR_CERT_COMMON_NAME_INVALID because when you go to https://192.168.1.31:32400/web you’re not actually using an SSL cert. That’s easily hundreds of lines of code.

g4m3r7ag on Mar 7, 2022

I don’t even see what benefits using Plex brings into this equation when most everybody uses Radarr, it would be neat for a project just used Radarr’s API to discover what GAPS is doing, but I digress. I hope the developer sees some benefits to having a like 10 lines of code added to support SSL.

onedr0p on Mar 7, 2022

Are you running a reverse proxy container? You can point GAPS at http://plex.mydomain.com:80 and as long as the reverse proxy auto redirects to https then it will connect through the proxy with secure connections set to required.

g4m3r7ag on Apr 9, 2021

I noticed that my Plex Image was runing on network HOST, but my GAPS image was running on network bridged. When I put both images on network host the connection worked
