dsarlis: good idea. I tried using Google DNS, but unfortunately it didn't work. Still getting the "network interference" message.
(disclaimer: this idea is dup'd from another post I made to a less-popular thread on this topic-- I am reiterating so more folks will see it)
I captured traffic inline between my Samsung 6050 and the internet while attempting a HUB login. The capture shows a TLSv1 Fatal Error due to an Unknown CA when setting up an HTTPS connection with Samsung Electronics. I think that is the problem (or one problem). Samsung is using a CA that our TVs didn't ship with. Regardless, if they can add the new CA to our TVs, that would fix the issue (assuming I'm not off in the weeds). This might be possible via the "firmware update" process. Hopefully, they move to a newer version of TLS while they are at it.
If anyone knows how to peek at the 6050's certificate store or has any insight into the feasibility of getting a CA update (or has another theory) I'm all ears.
