I don't know what provider you have, but if you have Comcast, their cable modems have software which detect "threats" and will drop connections to any system considered a "threat."

I triggered this by portscanning one of my own Digital Ocean droplets to make sure the Firewall was behaving properly.  Then I lost connection with the droplet, although I could get it via tor, or in the method you describe.

Note that, I was scanning the remote server *from* home -- the packets bouncing back to the port scanner were what tripped this "feature."

I had to actually write to Comcast and tell them to knock it off.  This is part of some new home security threat detection thing.  I was able to reconnect in a few days. Comcast never wrote back; I don't know if the block expired naturally or they did something on their side.

I mention it only because it was quite recently I found myself wrestling with this.  It was irksome; I get why they think it's a good idea but probably like most here I don't want or need their help in this regard.

If you're not using Comcast, well, forget everything I just said :)
