jwt_auth_no_auth_header error on validating WordPress REST API JWT token

I was facing the same problem, until i change the order of lines on my htaccess.Initially,i put the lines

RewriteCond %{HTTP:Authorization} ^(.*)RewriteRule ^(.*) - [E=HTTP_AUTHORIZATION:%1]

at the end of the rules.

After those lines where only after the RewriteEngine On, the error jwt_auth_no_auth_header was fixed.On jwt authentication for wp rest api

<IfModule mod_rewrite.c>RewriteEngine OnRewriteCond %{HTTP:Authorization} ^(.*)RewriteRule ^(.*) - [E=HTTP_AUTHORIZATION:%1]RewriteBase /RewriteRule ^index\.php$ - [L]RewriteCond %{REQUEST_FILENAME} !-fRewriteCond %{REQUEST_FILENAME} !-dRewriteRule . /index.php [L]</IfModule>

In case someone else faces this issue, this code that I added to .htaccess is probably not working

# Enable HTTP AuthRewriteCond %{HTTP:Authorization} ^(.*)RewriteRule ^(.*) - [E=HTTP_AUTHORIZATION:%1]

So in the plugin file jwt-authentication-for-wp-rest-api/class-jwt-auth-public.php, look in the function named validate_token, after the $auth check fails I added this piece of code :

if (!$auth) {    $allHeaders = getallheaders();    $auth = isset($allHeaders['Authorization']) ? $allHeaders['Authorization'] : false;}

This will get that Authorization header and JWT will work as expected
