I have a working Discourse instance on a GCE instance. I have email working through Mailjet by setting smtp\_port=2525 I am now trying to enable HTTPS. My reading of [Set up HTTPS support with Let's Encrypt](https://meta.discourse.org/t/setting-up-lets-encrypt/40709) is that I just need to uncomment ```plaintext #- "templates/web.ssl.template.yml" #- "templates/web.letsencrypt.ssl.template.yml" ``` in app.yml and set `LETSENCRYPT_ACCOUNT_EMAIL` to the email address I have registered with Mailjet, which is the same as `DISCOURSE_DEVELOPER_EMAILS` and the `From:` address used by Discourse, and then rebuild and restart Discourse with ```plaintext sudo ./launcher rebuild app ``` After that LetsEncrypt/HTTPS should just work automagically if I understand the instructions correctly. However I am finding that Discourse just becomes inaccessible after that. It becomes accessible again if I undo the above changes and rebuild again. Am I missing something? Is there anything special needed on GCE? I currently use the GCE external IP as `DISCOURSE_HOSTNAME`, which is working fine with regular HTTP. Do I need to set up a DNS domain and hotname to wok with LetsEncrypt? --- _[View the full topic](https://meta.discourse.org/t/minimum-needed-to-get-letsencrypt-working-on-a-gce-instance/64853)._
