XYplorer Beta Club

I guess this is the proper section to post this help question. Though it isn't related to the program.

Until today, I have never had a problem getting to the XYplorer web site and forum with my main home (land line) internet connection.
Now I am getting 'unable to connect to server', 'unable to resolve host name', and other messages depending on what device and browser I am attempting to connect with.
At the moment I'm at least able to connect fine using my cell phone carrier.

Yesterday I updated Pale Moon to the latest version on my laptop and figured this may have been the cause. I went through their recommended troubleshooting steps and still can't connect.
So then I tried on a different machine using IE, a tablet with a stock web browser and then my phone with still a different browser. All set up to access my home WiFi. And I still get the errors.
But as mentioned above, I am able to connect no problem using my cell phone carrier data connection. Why not my normal land line?

I'm able to visit and/or log on to other sites I frequent with no problem. I've also tried visiting various miscellaneous sites with no problem. XYplorer.com is the only one I can't reach.

Has anyone else ever had this problem? Or can suggest something else to try or a web site/forum that may help answer what's going on?
I'm in the U.S. in case that could have anything to do with it.

Thanks in advance.

Update
No longer a problem. It is working again on my main land line connection. Somehow, it fixed itself after about a day.
The gremlins must have gotten bored and moved somewhere else.
