Tutorial学習中のメモを再編集しています。

rails server 504eroor

AWS Cloud9
サーバーを起こしてプレビューを見ると504 Gateway Time-outとなっている。
プレビューをずっと見ていたわけではないので関係があるかは分からないが、jQueryとbootstrapを追加したのちに発生

$ rails s

（省略）
Cannot render console from xx.xx.xxx.xx! Allowed networks: 127.0.0.0/127.255.255.255, ::1
   (2.0ms)  SELECT sqlite_version(*)
   (0.2ms)  SELECT "schema_migrations"."version" FROM "schema_migrations" ORDER BY "schema_migrations"."version" ASC

結論

再起動したら治った。

以下奮闘記

2つ参考にして記述

\# config.web_console.permissions = '27.83.241.88'
  config.web_console.permissions = '0.0.0.0/0'
\# config.web_console.permissions = '27.83.241.88'
  config.web_console.permissions = '0.0.0.0'
\# 504 Gateway Time-outへの対処

We do not recommend using your AWS root account to create or work with environments. Use an IAM user instead. This is an AWS security best practice.
