IKEv2-ERROR:: Packet is a retransmission

I am unable to connect  anyconnect to Flex VPN server. 

I am getting IKEv2-ERROR:: Packet is a retransmission for a few tries debug information

 

eventually “failed to receive the AUTH msg before timer expired”?

 

I just wanted to confirm all evidence is pointing towards that it’s a NAT issue?(blocked ports)

 

My ISP router is being used as the WAN interface I have a static public IP address on the iSP router.  Port for IPSec/VPN has been forwarded to the Cisco routers interface.

 

any help or alternatives would be much appreciated.

Update: This was a version error, using wrong version of anyconnect, this has now been resolved.

 

this is due to 4.9 a lot of hash/cryptography  where removed!

 

currently using 4.8, seems to have solved all issues.
