@ivcrn2 It's all good...
Properly set DNS is a critical thing to making sure things are in working order. It's good to know you were at least able to determine the cause of the issue.
As for IP address issues, there is a way to check to see if this is the issue. When it's not working, open a web browser and point it to this link:
https://tracker.gaytor.rent/stmdd/
If a stats page loads with the tracker back-end stats, then it is not your ability to connect to the tracker back-end, however if the page fails to load when it's not working, it means that you're not able to reach the back-end, which may mean your current IP address is being blocked by our DDoS protection software.
When this happens, the easiest fix is to use a VPN, or if you're already using a VPN, you may need to change VPN server locations to get it going again.
