SAP ByDesign Connection suddenly stopped working

Hi Guys, 

I had an ODX connection to a SAP ByDesign instance that suddenly stopped at the end of last week and spit out the below error log. I am looking for any ideas on the direction to go. From how I am reading the error, I am assuming its originating at the ByDesign end, and I need to find a location to whitelist DiscoveryHub. (doesn't explain why it was working then suddenly not working without any other changes).

 

Thanks for any help.
