GCPでDiscourseの再構築ができません:GitHub接続エラーとポート443の問題

The fact it failed to connect after only 3ms means the problem lies on the host or very near it.

What changes have you made on the host? Have you started a firewall? Perhaps it’s overwriting the necessary forwarding rules for docker.

Start with examining the IP connectivity of the container.
