Yes I have seen a lot of this today and also on occasion over the last few months.
I ran a traceroute to the domain while this was occurring and found that the packets were all getting to the destination even though it is quite far from me (coming up on 15 hops) so I expect that the problem is on the domains side, failing to respond in some capacity. Did not have more time to diagnose what the issue may be further though.









Reverse proxy/SOCKS5 works well in my experience.
I have a little computer on my network which runs my VPN - then on that computer I have ssh listening on a non-standard port that my VPN’s dyndns links up to a human readable hostname with a different port.
If I want to watch stuff off-network I just have to ssh -D to that hostname and port and then configure a browser to use the connection as a SOCKS5 proxy, then jellyfin and anything else I’m hosting works as if locally through that browser.
The ssh is key based as well, not password based - haven’t had any incidents in doing it this way.
