Thank you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. It sounds like we just may need to deactivate and reactivate the account using new credentials. I'll leave steps down below on how to do so.
First thing I'll recommend is to save a backup to revert back to just in case. You can find how to do so down below.
Next we'll try deactivating all of the accounts. You can do so by following the article listed down below.
Once all the accounts are deactivated go ahead and follow the article here on reconnecting the accounts.
Once you're able to try this out let us know how it goes! If you have any issues connecting and we'll take another look.
