Proxy "Connection Refused" in Web Filtering

The url is uzing an alternate pirt.   The port needs to be permitted on the Misc tab of Filtering options.

Have you done rgis?

Thanks for the Speedy Response Douglas.

Its not that, I have permitted all of the requested services in the Filtering Options -> Misc tab.

Previously i was getting a "Target service not allowed" error which was addressed by allowing the services.

Kind Regards

Then it is probably a ciphersuite incompatibility, on the assumption that https inspection is active.

UTM dropped all support for TLS1.0, but some older servers do not support tls1.2.

Try disabling https inspection for this site and retest.  If my theory is correct,  chrome should give you a "not secure"7 warning in the address bar, but will let you connect.

You can also try testing the site using the server test option at ssllabs.com, but it may not work on nonstandard ports.

I have added a HTTPS rule to the exceptions however i still get the error.

I am not using a web browser to connect to this port. It is being used by a fileshare software through the proxy feature.

Try creating an exception to bypass authentication for either source or destination address.  Non-browser applications cannot provide the NTLM information needed for Active Directory Single Sign-on

I have also tried doing this but to no avail.
