Sophos connect using provisioning file for multiple gateways

Hi,

I have configured the Connect Client with the following config[
{
"display_name": "XG_SSL-VPN",
"gateway_order": "in_order",
"gateway": [ "xg1.some.company.com", "xg2.some.other.com", "xg3.yet.another.com" ],
"user_portal_port": xxx,
"otp": false,
"auto_connect_host": "",
"can_save_credentials": true,
"check_remote_availability": true,
"run_logon_script": false
}
]

While testing for failover, I am facing multiple issues

1. When I made first 2 Gateways unreachable (deliberately),  It tries to reach Gateway 3, and SSL VPN is established, but the connect client stuck at Authenticating stage. But it has already established. Please advise how to resolve this

2. Sometimes it doesn't even failover to Gateway 2 when Gateway 1 is failed. Gives Failed to load the connection.

Another question is, Does it failover to gateway 2 when the gateway 1 is reachable, but there is no policy for that user in gateway 1 firewall

Please advise

Thanks
