error="Timeout while reading response from Server"

Thanks for posting your question here, George.

statuscode="504" [...] fullreqtime="61041279" means the server doesn't play well with proxies and that the proxy timed out after sixty seconds.  If the timeout were increased, the result would be the same.  With this error, if creating an Exception for Anti-Virus for online-update-software.alcatel.com doesn't solve the problem, then you'll need to skip the proxy for that FQDN.  In Transparent mode, this is done by adding a DNS Group for the FQDN to the Transparent Mode Skiplist.

Bob, I had several cases with my clients in the past where increasing this timeout value actually resolved the problem.

In almost all of the cases problem was related with B2B online portals or Government sites, while searching for a query where local database services and Internet links were not optimized for a heavy traffic:

Last time I run that command was with 9.315 firmware version, will try it in my lab environment with the latest one.

Your screenshot shows a typo.  respone rather than response.

Hello. I open the network group for online-update-software.alcatel.com and tried again but nothing. The errors are:

Hello Michael, you are right about the typo, but increasing the timeout didn't solve the problem as Balfson said.

The traffic is still going through the proxy and there is no exception for antivirus. Try the exception first. In the future, please post complete log lines  including the date and time.

Hello. I removed Transparent Mode Skiplist exception and left only antivirus exception for online-update-software.alcatel.com. The logs are:

The traffic is still being captured by the proxy, so either your entry in the Skiplist has an error or you are not using the proxy in the Transparent mode.

Hello Bob. I uploaded some screenshots to check. Can't see something wrong in the Skiplist or the AV exception.Screenshots.docx

(Grasping at straws here.)  Does the Alcatel DNS Group definition violate #3 in Rulz? That's in the "Destination" list, right?
