Agent doesn't work without certificate, doesn't seem to print an error either

After compiling arduino-create-agent and running it manually, everything seems to work at first, but the Arduino Create Editor can't connect. As far as I can tell, the problem seems to be that the certificate files are missing, and the agent doesn't open an HTTPS port without them.

I had installed arduino-create-agent using the installer previously. I got my compiled version to work by copying the following files from the install directory to the directory where my compiled agent executable was:

• cert.cer
• cert.pem
• key.pem

I don't know if my workaround is the correct way to handle this, but it would be great if

1. the correct way to handle this would be documented in the README and
2. if the agent failed in an obvious way when the certificate is missing.
