Access from mobile device clients suddenly stopped working. Worked with SonicWALL and the firewall appears to be forwarding correctly. To further validate, the firewall settings were backed up and restored to a previously known working configuration.
Internal clients can access the https://server/owa
without any trouble, but external clients cannot access OWA.
File Not Found
The requested URL was not found on this server: /owa
Access to https://server
works and displays the SonicWALL Network Security Login (SSLVPN).
No known changes to the server configuration aside from updates.
Any advice would be greatly appreciated!
