Good job for reconnecting your bank to QuickBooks Online, jd-be.

We can try other troubleshooting steps by logging in to your account through a private browser. This is to verify if the issue you're currently experiencing is caused by a browser's cache. 

Then, go to the Banking page and look into the bank if you can still see the error. If it didn't show up, you can switch back to the main browser and clear the cache. You can also try using other supported browsers to isolate these kinds of issues. 

You can take a look at these references for more details on how to handle your bank feeds:
