Maybe the problem is with your modem or router. Try turning them off for a couple minutes and turning back on.
Thanks for those suggestions. Unfortunately, I tried that last night and again this morning, but didn’t fix the problem.
But I am thinking that the fix lies with resetting SOMETHING, just not sure what. I thought re-entering my IP in the proper screen(s) and clicking on “Apply/OK” would re-initiate the connection, but that wasn’t the case.
