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. 

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

I didn't find certificate in CA

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,
