NGINX のパスを CloudFlare でサブドメインに書き換えるとリダイレクトが多すぎる

NGINX のパスを CloudFlare でサブドメインに書き換えるとリダイレクトが多すぎる

次のようにURLを書き換えたい:
https://documentation.domain.com/loginからhttps://app.domain.com/login
https://api.domain.com/loginhttps://app.domain.com/login
任意のサブドメインからURL {anything}.domain.com/login へhttps://app.domain.com/login

https://app.domain.com/sdkshttps://documentation.domain.com/sdks(すべてのクエリパラメータが保持されます)(すべてのクエリパラメータが保持されます) 、URLが{anything}.domain.com/sdksの任意
https://api.domain.com/sdksの サブドメインからhttps://documentation.domain.com/sdks
https://documentation.domain.com/sdks

https://app.domain.com/restApihttps://documentation.domain.com/restApi(すべてのクエリパラメータが保持されます)(すべてのクエリパラメータが保持されます) 、URLが{anything}.domain.com/restApiの任意
https://api.domain.com/restApiの サブドメインからhttps://documentation.domain.com/restApi
https://documentation.domain.com/restApi

Cloudflare SSL を Full Strict に設定しました。Fulll/Flexible に変更しても何も変わりません。この設定はほぼ機能します。これは機能しますが、ERR_TOO_MANY_REDIRECTS が発生します。これを修正するにはどうすればよいですか? どこが間違っているのでしょうか? 助けてください
