Site to Site SSL vpn

Hello there,

Thank you for contacting the Sophos Community.

What version of the XG is running?

Are you receiving this in the Sever or on the Client-side?

Hi sir,
I am using SFOS 18.5.2 MR-2-Build380 in client end and SFOS 18.5.1 MR-1-Build326  in Server End firewall. 
Getting the message in the firewall configured as server.  at client end the tunnel is showing red but at server end tunnel is showing green. 

the same user authentication failed showing that user found in the server certificate.

After restart of Data Center firewall, problem solved. 
Thanks all for your support.
