502 Error (When HTTP scanning enabled)

Good Afternoon,

Since upgrading our XG210 to MR2, we have been experiencing frequent (but not constant) 502 errors when accessing various websites. The two that have been pointed out to me thus far are:

* http://www.bangordailynews.com
*
 http://www.amazon.com

This issue occurs whenever HTTP scanning is enabled (and thus is not an issue if we attempt to access those sites via HTTPS) and irregardless of Application / Web Filter policy applied. When error is occurring, Web Filter log still shows that the traffic is "Allowed."

Has anyone else experienced a similar issue? Besides creating destination-based rules to disable HTTP scanning for those sites, what are some potential solutions to this issue?

Best Regards,
Justin

  • Hello,

    We are using Sophos vUTM ver 16.01.2 in Trial period , but trial period was ower nad all licenses are expired.

    This morning suddenly we came across errors http 502. When we disable the scanning HTTP in L2W rule , problem goes away.

    We can not install new firmware because Sophos does not allow because of support  license is expired. After we activate the licenses ,we will check again and post the last situation.

    Regards,
