If you get TokenExpired message right after logging in to your App, please access to your WordPress folder -> Opening .htaccess -> Put

SetEnvIf Request_URI ".*" AllowCountry
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1
</IfModule>
# END WordPress
SetEnvIf Request_URI ".*" AllowRestApi

or Put the following code to .httaccess

<IfModule mod_setenvif.c>
<IfModule mod_headers.c>
<FilesMatch "\.(cur|gif|png|jpe?g|svgz?|ico|webp)$">
SetEnvIf Origin ":" IS_CORS
Header set Access-Control-Allow-Origin "*" env=IS_CORS
SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1
</FilesMatch>
</IfModule>
