Does not work with Let's encrypt generated .pem certificate files

[jkulak]

Describe the bug

Server runs on http as expected. I try to switch to https:

#### HTTP/2 + TLS
http2 = true
http2-tls-cert = "/home/www/deployment/fullchain.pem"
http2-tls-key =  "/home/www/deployment/privatkey.pem"

I tried with with cert.pem, chain.pem as well - same error. Server does not start.

To Reproduce

1. Generate certificate files following: https://certbot.eff.org/instructions?ws=other&os=ubuntufocal
2. Edit /dev/config.file like above, make sure paths are correct
3. Run docker run --env SERVER_CONFIG_FILE=/config.toml -v /dev/config.toml:/config.toml -p 8787:80 joseluisq/static-web-server:2.12

Expected behavior

Webiste runts over https.

Can you confirm please how the format of your private key looks like? Does it start with BEGIN EC PRIVATE KEY or BEGIN RSA PRIVATE KEY?
Since EC private keys are not supported on this release yet. But in the next one.

[joseluisq]

Does any progress on that using latest release?

[joseluisq]

Closing this since #207 seems related and we already support EC private keys #208.
Feel free to re-open the issue if necessary.
