Has anyone recently started having issues with the FD/SF integration? Ours was working for 2 years and then stopped. On the SF side, it just showed nothing under the tickets list. When I try to update the API key, I get the following error:

Unable to connect to Freshdesk. Please check the domain URL and "credentials"

I am working with FD support but they seem to be stumped so I'm hoping that someone else has run in to this issue. We are able to get the connection to work in our SF Dev environment so we do have everything entered correctly. We also attempted uninstalling and reinstalling the integration and that did not fix it.
