Anyone ever run into this issue? Here’s what happened. Salesforce connector just finished integration last week. Everything worked - I set up objects to sync, they were syncing just fine (synchronized data extensions were created and populating). Then, for some reason it stopped working due to a number of IP addresses not being whitelisted.
No objects would sync and we could not add new objects.
I had client whitelist all IPs, and then after sometime, still not working, going into Salesforce Integration, we see this. Account is disconnected. Customer goes to reconnect and inputs the sales cloud credentials and gets this error.
