For years I was able to upload new pfx files for SSL binding on Azure App Services using the OpenSSL creation method in

What ways can this issue be resolved?

CodePudding user response：

App Service private certificate requirements

App Service private certificates must meet

Use this thumbprint to export the cert to a new pfx file, replacing the -Cert, -FilePath, and password -String arguments:

Export-PfxCertificate -Cert Microsoft.PowerShell.Security\Certificate::LocalMachine\My\B56CE9B122FB04E29A974A4D0DB3F6EAC2D150C0 -FilePath 'newPfxName.pfx' -Password (ConvertTo-SecureString -String 'MyPassword' -AsPlainText -Force)

Azure should now be able to validate the new pfx file output.
