I'm facing a weird situation, just look at the following code in a blade file, and the output of it

Blade

{{ url('xero_invoice_authorised') }}

config app url - {{ config('app.url') }}

env app url - {{ env('APP_URL') }}

Output

http://xxxx/xero_invoice_authorised
config app url - https://xxxx/
env app url - https://xxxx/

url() is returning the URL as http: but it should be https:.

The system is inside a docker container.

I have run all commands to clear the cache, view, routes, and even ran optimize command.

Can anyone suggest to me what's wrong with my configuration? or any method to rectify this issue?

I need {{ url('') }} to return the APP_URL in the .env file.
