Compilation ipa credentials problem : IOS

Hi All,
I have an app.
It’s app id (in the config.xml) is weel configured in the console of apple developers.

I’ve created all required files on ubuntu (.cer file, provisioning and i also have the p12 file)
I’ve got all the required files.

But When Uploading my app (under package->certificates) in the Pro platform, i get the following error:

“There was an error while submitting your credentials. Certificate, Provisioning Profile, or Cerftificate password invalid.”

I am sure the password is correct.
I’ve followed each step given in this link :

What am i missing? (I also made sure the bundle id on my app account matched the one on the config.xml file)

Please help ?
