Hello @flstc51
Thank you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. That is a bit odd since you had it previously work well. To narrow down the issue lets see if we'd have a similar issue pop up in a test file. This will give us more information whether it's an issue with the file or the connection. I'll leave steps down below on how to do so.

You'll see it under the third step down below. Once you get a chance let us know what you're able to find out! With more information we'll see what we can do.
Thanks,
Quicken Francisco
