Lets encrypt renewal & runtime config

How to deal with the renewal of the keys on the Phoenix side? Do I have to restart the Phoenix server or will Phoenix read the updated files in due time?

If those files are updated, I think you don’t need to restart anything and the new certs will be eventually picked up. FWIW site_encrypt forces this manually by invoking :ssl.clear_pem_cache.
