The reverse proxy header configuration is incorrect, or you are accessing Nextcloud from a trusted proxy


After I successfully installed the Nc21 my overview are all passed and no warning but after I installed the Notify Push (HPB) and working using the official documentation I got a warning on my overview

Looking for your kind assistance what I missed or need to add to complete my configurations.

May I know if this is critical? If yes will not use for now the Nofity push (HPB)

Thank You and More Power
