VPN tunnel cannot route one destination/ports more then a minute
I had recently established VPN tunnel from Cisco 2800 series router to VPN concentarator , this is simple a LAN to LAN VPN tunnel and i can access servers through the VPN tunnel.so far so good but i am facing issue with one destination/servers which is hosted on https.I can access this destination through VPN tunnel but with in minute i loose it(but other servers works
it means the VPN tunnel is not down) and if i reaaplied VPN tunnel ( remove crypto map and apply again) , the server access starts working but only less then 1 minute.. it's difficult to hone down it server issue ..as when the server access stops working if i tried to do telnet on the server(port 443) it failed but if i reapply the VPN tunnel and telnet on Port 443 start working but less then 1 minute.
however more confusing is that telnet always work on this server for port 80.so it means it's not routing issue.
but on port 443 it works for less then i minute and after resetting the tunnel it starts working but for 1 minute only ...
any pointes to resolve this issue will be very helpful.

In Syslog I also se...
