Hi john marion It seems under Web > General settings > Action on malware scan failure > Set to block with your XG and malware scanning seems to fail for the above URL which you have mentioned at Proxy or DPI which is generating an alert. Now it could be a temporary issue around that time which was failing the URL scanning only at that moment however if the issue is static and still persist then you may re-produce it by accessing that URL to validate the logs of proxy and antivirus and if needed may log a support case to check it further.
