yeah, that happens to me as well, people post things and I’m on the road a lot, and sometimes they work later on.
Our company uses a Tor service too, and sometimes links just won’t work for some reason, they are blocked without a real IP address in some locations.
The UP of Michigan does that to me often, then I get about 40 miles into Wisconsin and it works great (Illinois never gives me problems, probably because of Chicago).
I wish I could tell you more, but I know butkiss about computing.
