Situation: After renewing their Certificate for Globalprotect, the client has a problem to login VPN with Connection failed error.
Troubleshooting: When renewing the certificate, the client might exports the current SSL certificate instead of generating the CSR. Or they enter using different SSL name. We fix the problem by generating a new CSR with different name, export and rekey in GoDaddy. Then import it in GlobalPrtect. Deleted the old SSL and modify SSL/TLS Service profile to use the new SSL.
