I have recently discovered that when operating pfSense Fail Over mode Roundcube authentication fails with a "gateway timeout".
Everything on all servers is working as it should.
The roundcube login screen appears but when you submit it eventually returns a gateway timeout.
(this is only when pfSense is operating through its backup firewall)
Not sure if this is a pfSense issue or a Roundcube issue.
Any advise on how to fix this is appreciated.
Thankyou
