I'm having this error when i tried to connect to VPN server. I am totally sure that connection group and the user authentication are ok.
It seems to be a IKE phase 1 problem. The output of debug isakmp level 1 & debug crypto ipsec 1
ERROR: IKE failed trying to create a session manager entry
Removing peer from peer table failed, no match!
Error: Unable to remove PeerTblEntry
In addition i tried changing the isakmp policy, but the problem continues. NAT-T is enable and i tried in differents PC with the same result.
I attach the output of the debugs in level 1 & 10 and the asa config.
VPN client: 5.0.05.0290
Thanks in advance.
