SSL certificate error

Server Version#: 1.41.3.9314
Player Version#: web player

I cannot get my server to work outside my network, rather I do manually port forward (with the port being forwarded in my router) or I do the automatic one I keep getting this error

[HttpClient/HCl#4c5] HTTP error requesting GET https://xxx-xxx-xxx-xxx.c49b81cefb62477d9b97e090f7a35a50.plex.direct:32400/identity (60, SSL peer certificate or SSH remote key was not OK) (SSL certificate problem: unable to get local issuer certificate)

It always shows my server available outside my network for a short period than says it’s not. I read an article saying that you need to post on the forums for an employee to manually reset the cert, I have spent hours trying to get this to work with no success.

Having the same issue now as well, started a few days ago all of the sudden after working fine for months.

Using Plex Linux if that matters

Most of these are either DNS or plex cert issues, without server logs its near impossible to diagnose.

Sure, attaching logs here.

Probably related - if I try to sign in to the Plex forums from within my network, I get hit with Chrome’s SSL warning on https://plex.tv/api/v2/discourse/sso.json?sso=... and I can’t continue past it:

I’m currently traveling and from my current location I don’t have that issue.

Will try to contact my ISP since it seems like it might be something on their side.

Quite likely something sits between you and the plex servers and is intercepting encrypted traffic. It then decrypts it, inspects the contents, then again encrypts it with its own security certificate. Which is what causes the error message, since the certificate and the domain plex.tv don’t fit each other.

A typical M.O. of corporate firewalls, but also third-party anti virus software on your own computer or router.

On the computer where I’m just trying to sign in to the forum I don’t have any anti-virus aside from the standard one included in Windows 11.

Where I’m running Plex, I don’t have any anti-virus.

Both are in a home network, not anything corporate. What else can I check?

Then the “corporation” might actually be your ISP.

Any other suggestions of things to try or things to check?

It seems like me and OP have similar issues, but I doubt we’re on the same ISP…

Many ISPs are pulling the same trick.
Tell your ISP to keep their noses out of your data packets.
Some ISPs are trying to sell this as a good thing. They tend to call it “internet security” or similar. See if they provide an OFF-switch for such features. Maybe it can help.
