Inconsistent ability to connect to server
Hey all- relatively inexperienced so I may be missing something dumb. I set up a basic LAMP server and for around an hour wasn't able to access it through pinging, putty, or using online SSH testers.
Then, all of a sudden, I was able to putty in. I set up MYSQL and configured a single PHP page, which I and a friend were able to access.
I took a break, and now I cannot access my server again, through any method. Can any advise? Thanks!
