Hi, I am trying to use LetsEncrypt for using on my Qnap nas. The Qnap asks three certs:
Certificate: I copied the contents from cert.pem there
Private Key: I copied the contents from privkey.pem
Intermediate Certificate: I copied the contents from chain.pem (for upload)
There is btw a fullchain.pem too but I didnt use that one.
Applying the keys gives the error message: Intermediate Certification validation failed.
Any idea how to solve the Intermediate Certificate Issue? Thanks in advance.
