JWT The token could not be parsed from the request only on live site – CPanel

I have built a custom API using PHP (version 7.0), specifically the Laravel framework (version 5.5.40) that uses the tymon/jwt-auth (version 1.0.0-rc.2) package for user authorization. Many of my controller functions use this line to get the currect user’s credentials:

$user = JWTAuth::parseToken()->authenticate();

I use Postman to test my api.

When I make api calls in my local environment, the authorization passes normally and returns the expected data.
When I make api calls to my live site API (hosted in my apache server), I get this error:

The token could not be parsed from the request

Since this error only occurs on my live API, I speculated that there is a problem with my API’s .htaccess file (which is by the way recognized normally by the application, I did some debugging and checked my apache error_log to make sure changes to my API’s .htaccess are recognized).
I tried adding these lines (and different variations of these lines as I encountered multiple suggestions while researching):

RewriteEngine On
RewriteCond %{HTTP:Authorization} .+
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

but still the error persists.
I tried adding this code:

var_dump($_SERVER);

prior to the:

$user = JWTAuth::parseToken()->authenticate();

and I noticed that on my live API these elements are missing from the $_SERVER array:
REDIRECT_HTTP_AUTHORIZATION, HTTP_AUTHORIZATION

Wasn’t the above .htaccess code meant to add these manually?
