Hey @EricPopelka - appreciate this context!  
While the developer side of things is still outside of my purview, I was able to find [this Community thread](https://community.hubspot.com/t5/APIs-Integrations/Couldn-t-complete-the-connection-An-error-occurred-while/m-p/778394), which addresses the same issue as well as the fix. Would you mind taking a look and providing any context regarding whether or not this helps?
