Hello,
I have a client who is having the same issue on his Samsung TV,
Below are the initial errors he got on his TV:
I am also doing Reverse Proxy on IIS and using emby.mydomain.com as the domain name ports 80 and 433. Also switched from Lets Encrypt to Zero SSL with no luck.
All the other clients have no issues on their Samusng TV. Also tried on Emby 1.7.0 (From store) and 1.8.7 From USB installation with same issue.
Can someone advise on what could be wrong.
Than
BTW, I don't think the clients support using a path like https://server.name/emby. (ie : with a path on the end). Not sure if that is what you are also trying to do
I remember that this has come up before as an issue, but can't remember the outcome, or if it now works as expected.
I'm assuming you've also been through this
and check this
