I keep getting this error on 3 sites that I have hosted on Network Solutions. Network Solutions assures me that it's not a problem on their end. I can't get into the pages on any browser, but all other sites seem to be working fine. It also won't connect on my phone which uses my XFinity home wi-fi. My daughter also hasXFinityt in a nearby county and can access the site. She can also see it on her AT&T phone.
I have reset the modem, turned everthing off and on, flushed my caches, changed the DNS to 184.108.40.206 and 220.127.116.11.
What can be wrong?
The connection was reset.
What ended up helping me was to swap my modem for a new one at the Xfinity store. My own ip address was being blocked by my modem and no one could permanently remove the blockage. The new modem had no such blockage and has worked perfectly, solving the problem.
