Figured it out as soon as I posted it of course. I had an issue with the path. It should have been.
Now onto the next issue as it claims it does not match the key file...
Did you resolve the problem matching your serverkey.pem file? I am stuck there at the moment.
Was this ever resolved. I am finding myself at this same point. Problem matching my serverkey.pem file.
OK, I solved my issue. I don't think it would be an issue but check the file type of the cert. I tried importing a cert with the .crt extension and it didn't work. tried again with another cert, this time with the .cer extension and it went through.
Hope this helps anyone that comes along this post, although i was two years behind. Cheers.
