Totally baffled on web site error ...

[RCPWISC]

Well ....... this has taken another turn.  This is NOT a Linux problem it seems.  I just did a clean install of Win10, and I'm getting the same darn error as I did in Linux!  This is clearly something on the provider's end.  Now I hope we can actually figure out what the problem is!

Thanks to everyone for offering help and suggestions!  I got to learn a lot of stuff in these few posts!
