I got a dedicated server to work yesterday. My friend could join and we played for a bit. I come back next day, forward the port and it doesn't work.
I have tried everything (that I could find) and have had no results. I'm able to assign my PC a static IP but when I try to port forward to the IP, I check canyouseeme.org and it says connection timed out.
My subnet mask is 255.255.255.0 and my default gateway is my router's IP. I'm also using google's DNS (18.104.22.168, 22.214.171.124)
Here is my port forward settings: https://imgur.com/W2uzHscEDIT**
Apparently everything was correct and canyouseeme.org was being dumb
