User Portal SSL certificate problem

Question

Hi Guys, 
 
 i have renewed my certificate on my XG135, i changed the certificate under 
 Administration -> Admin & User Settings, but :

This site can&rsquo;t provide a secure connection 
 vpn.athenion.com sent an invalid response.

Try running Windows Network Diagnostics.

ERR_SSL_PROTOCOL_ERROR

someone has some tips? 
 the internal ip is correctly reachable, but from extern, the User Portal is not longer available.

Hello there, 
 Thank you for contacting the Sophos Community. 
 Are you trying to access using the FQDN or the Public IP of the XG? Try also using incognito mode, as sometimes the browser might cause issues after a new certificate for frequent site changes.
