Hi @Brucevankesselwhere did your server SSL certificate come from? 

[Brucevankessel 1]

i bought the cert from xolphin 
and it is a comodo cert

Strict vetting for SSL propagation delay can be around 5 days.  Has it been that long, since you activated the SSL?

This is a 2020 year model TV.

Samsung don't typically update the root and intermediate certificates on their TV, so if xolphin have started signing with a newer Sectigo certificate then this is probably the issue.

I suspect that this is most likely your issue, especially if the web browser is also reporting wrong ssl certificate. Unfortunately, if that is the case, there isn't really much that can be done to avoid it.  The other option is to avoid using https on the Samsung TV.

Looking at the root/intermediary certs in the ssl certifcate chain, they appear to have been generated from 2021 so it is very likely that the root certificate is missing in the TV.  Unfortunately it's very unlikely that Samsung will update them.

Quite some years ago the same issue occurred with LetsEncrypt certs which were very commonly used, and as far as I know, they still haven't been updated on older models.

I think plain http on the TV is going to be the only option.
