I'm having an issue with a certain website and am not sure where to start troubleshooting. I've had a personal website for many years and have never seen this problem before. Radomly but quite often when trying to access the url of my website I get the following error:

"ERR_NAME_RESOLUTION_FAILED The webpage at XXXXX might be temporarily down or it may have moved permanently to a new web address."

This only happens on my personal website. All other websites seem to load normally. Also, when I restart the router the website will load normally for a while until the error shows up again. So the problem must be either with my website or with the router. Nothing has changed on the website that I'm aware of.

I'm at a loss and don't have the technical knowledge to even begin to troubleshoot. If anyone has any ideas of what could be causing this, I would love to hear it, or please point me to the appropriate place.
