Importing the certificate in PA M-100 is not importing and not giving any error.
Create a certificate in PA or use the certificate third party signed Certificate. In our case I am using a certificate "PA Worldclass Cert" generated and singed by PA self signed certificate.
Export the certificate from Firewall and import it in PA M-100.
Status will show as uploading, but it does nothing and it stays on the same screen.
Open a debug session for web Gui by using the management ip address like https://10.50.243.14/debug
Select the button Clear debug.
Now import the certificate again and select the button refresh in web gui debug page
In this case the error says certificate name is invalid (keypair --> name 'cert_PA Worldclass Cert.p12' is invalid)
Which means the certificate name contains a space and M-100 is not accepting it with the space in the name.
If you remove the space in certificate name and reimport it, M-100 will accept it and will be imported sucessfully.
