Avast Premium Bank Mode says Access Denied

I have Avast Premium and have never had a problem using Bank Mode until today 4/25/20.

When I tried to sign into my bank I got the error message-
Access Denied
You don’t have permission to access “http://onlinebanking…” on this server.
Reference #18.44f7268.1587822934.45a64d5
(I removed the info after "http://onlingbanking )

How can I fix this?
