few remote users on global protect 6.2.8-c948 are facing connectivity issue "the network connection is unreachable or the portal is unresponsive. The global protect logs doesn't show any errors but users are facing difficulties connecting to the global protect VPN.

Same on 6.3.3-c1121. This error keeps coming back in every second or third version. The programmers mess it up every time. For us, it works either with an older version, 1016 (which has security issues), or by disabling IPv6 on the devices. Maybe it works for you, too?

Thanks, @M.Falk310364 . the issue got resolved upon few other troubleshooting steps but which one recommended upgrade from GP 6.2.8-c948, as getting suggested for 6.3.3-c1121 recommended upgrade.
