action :server-rst

[amara]

may anyone help me

firewall fortigate DMZ  log action :server-rst     the client can't reach url web server

"vpn connection site to site ipsec between asa and barracuda" 

[boneyard]

it suggests the server resets the connection the client tries to setup.

first check would be the server, does it see the traffic and respond with a reset for some reason?

Check local FW on destination server, probably denied by that. Or maybe some kind of IIS / nginx denial.
