I have this error
Error 32 An error occurred while signing: Failed to sign bin\Release\app.publish\setup.exe. SignTool Error: The signer's certificate is not valid for signing. SignTool Error: An error occurred while attempting to sign: bin\Release\app.publish\setup.exe MyProject
My certificate expired in 8/23, I've tried to create a new certificate in the signing tab and everything is fine; but when I click publish I get this message:
The application is signed with a different key than the existing application on the server. Do you want to overwrite it?
If I choose 'yes' the users could access the new application version without any certificate issues?

According to Microsoft itself, if you are targeting .NET 4 or later "you can just replace your certificate, issue an update, and go to lunch while the rest of us struggle on."
