I had several cases where suddenly Websites not work. after a lot of tests. I was only able to solve it because I changed the DNS back to the provider DNS. I never found what it caused.
Then I changed it back. that worked some Weeks, then i had again Problems.
Now I use again and permanent the provider dns.
