I'm running ubuntu 14.04 and am unable to connect to any remote mongodb server on my home network. I'm pretty sure it worked only a month ago. Furthermore, I have no problems connecting from my work network.
For example, I have an aws server running mongodb. I can ssh to it, but trying to connect with mongo results in the uniform connection error ("couldn't connect to server... connection attempt failed").
Any suggestions on how I can troubleshoot this?
EDIT: I just confirmed the same behavior on a windows machine. Could it have to do with my ISP?
EDIT 2: turns out it was a problem with the router. I'd still be interested to know of there's any way to identify where the issue is from the computer, without going to the router. Though even if I had looked at the router I wouldn't have known that it was blocking all non-standard ports.
