After upgrading from 9.1.13-h to 9.1.14 issue was noticed (not sure if it was present earlier) - in about a week/two GlobalProtect stops responding - even portal page is not opening from the browser, so also GP client connection fails. It is not getting to authentication or anything further. Portal IP is responding in general - pings are fine and even initial TCP 3-way handshake is seen in the captures. HA failover to secondary helps. Rebooting failed device helps. Rebooting only dataplane also helps. Took some information and will research that, not going too deep here, but, by any chance, has anyone seen something like this?
