Normally a miner in a colocation needs to be set on a static IP in your case the IP the colo is giving you.
No need to work with ports to setup a miner. Just IP and Gate and DNS
And every good colo, gives customers a web interface to log into the IP. I think you need to ask them about that
So I talked to colo. They haven't touched the miner and it is in the same spot connected as it has been for the past month+. I have been able to connect to the miner remotely through the IP without any issues for this past month. But for some reason now I can't get the IP address to load anything. The colo confirmed the static IP address is the same and hasn't changed. I can ping the IP address fine, and it is hashing away in the mining pool. Any ideas?
