WordPress no longer recognizes me

I have been on WordPress since 2013. I have been able to get on wordpress to manage my website just fine all this time. Now I get an error saying “Hmm. We’re having trouble finding that site. We can’t connect to the server at gdmig-patlintner.com.”

My website also does not look correct. My tabs are very different and when I click on one, it comes up saying the exact same error. I have not changed any themes on my website for several years now.

I go to my last email with WordPress and the link I have been sent even does not work! This is my last email I got from WordPress which does not work….

“`Howdy! Your site at https://patlintner.com has been updated automatically to WordPress 4.9.15.

For more on version 4.9.15, see the About WordPress screen:

I was in contact for over two hours with Go Daddy and they said everything was good on their end.

I tried “lost my password” and wordpress sent a link for me to reset, but it does not work (tried over 14 times and counting).

I am at a loss of what to do right now and even my IT guy who helped set me up in 2013 is confused!

If there is any help I can get I will be much appreciative!
