Hi there, 

I'd like to know the name of the affected bank. That way, I can check if we have an investigation about this error.

Also, if none of the steps from the previous replies help in downloading your bank transactions, I suggest contacting our Support Team. They can open a ticket about this issue so that our developers can come up with a permanent fix. Please follow the my steps above in reaching out to them.

Please keep on posting if you need anything else. I'll be here!
