After configuring Global Protect, installing the client and trying to connect, the following error occurs on the GP Client:
GP Client Error: Gateway xx.xx.xx.xx : Protocol Error, Check server Certificate.
To fix this issue, check for the following:
- Incorrect time settings on the firewall.
- Check the certificate's validation dates (valid from and valid until) to make sure the date range is correct.
- Check the Time Setting on the firewall. Use NTP if the time stamp isn't accurate.
