certbot to generate ssl cert for my domain.
Then I use the following commands to copy the content to clipboard
cat ./letsencrypt/live/mycompany.com/cert.pem |pbcopy cat ./letsencrypt/live/mycompany.com/privkey.pem |pbcopy
and paste into Google App Engine's "Add a new SSL certificate" dialog box.
However the private key is rejected due to 'The private key you've selected does not appear to be valid.'
(I have replaced the content with 'zzzz')
How can I convert the certbot output into the right format?
Also I do not know exactly what format and roles are those certbot generated files are in.
cert.pem chain.pem fullchain.pem privkey.pem
