Hi Alex,

Letsencrypt gives me a privkey.pem file that i convert to rsa this way : openssl rsa -in privkey.pem -out rsaprivkey.pem

Then i concatenate this rsa key with the fullchain.pem generated by letsencrypt wich includes the certificate and the chain certificate.

When i upload this file through the GUI i get the error.
