VPN AnyConnct, first login attempt failed

[thomas poeckl]

Hello;

I have the problem that my users need at minimum 2 attempts for a stable VPN connection with any connect.

Is there a known issue for this behavior?

ASA 5515-version 9.12(4), any connect 4.803052, 

Thanks + Sorry for my bad English, Greetings, Thomas

Hi,

Try disabling DTLS and see if that works.? If not, try lower the MTU value
under group-policy settings and see if it works.
