Guys, google GCE won't accept certificates larger than 2048 right now. When I create a cert using webmin the default is 4096 and I don't see any options to change/select key size. Can you add that to the letsencrypt section so we can set keysize when generating?
Error: The SSL key size is unsupported. The loadbalancer supports RSA-2048 and ECDSA P-256 certificates.
