Is this a self sign certifiicate or a CA certificate.

Adjust the date to proper date.

I'll take a wild guess and say that your date/time was changed before you attepted to connect, hence your certificates valid dates would likely not match up with 2013. Also explains why you can't connect to anything. 

[Rockwell]

change to correct, but when connect to GP, it will change to 2013 again

I didn't find certificate in CA

[santonic]

Are you saying that your PA date keeps changing to 2013?

Hi,

Please regenerate CA certificate and insert into SSL/TSL Service Profile after add that to your Globalprotect Gateway!

Thanks,

It shows that your certificate time and your local machine time are mismatched. plz, see your CA certification time.
