We upgraded from cyberoam devices to sophos recently. We now face challenges with accessing rdweb apps from the branch. The Rds server is located at HQ. The firewall rules for LAN to VPN and VPN to LAN are set to allow all traffic and any services. However now we can authenticate to the rdweb site but then when trying to run the rd apps it gives the error below. Everything was working fine before the upgrade. The HQ is on cyberoam CR200ing while the branch is on Sophos XG210. Any leads are appreciated.
