I´ve been trying to the app and I got this messager   net:: ERR_BLOCKED_BY_RESPONSE

And I found the solution , I hope this can be helpfull:

Go to youor cPanel 

Browse and find the .htaccess file , (you should download a copy , if something goes bad :/ )

On the .htaccess, paste this: 

<ifModule mod_headers.c> Header set Strict-Transport-Security "max-age=31536000" env=HTTPS Header always set X-Frame-Options "allow" Header setifempty Referrer-Policy: same-origin Header set X-XSS-Protection "1; mode=block" Header set X-Permitted-Cross-Domain-Policies "none" Header set Referrer-Policy "no-referrer" Header set X-Content-Type-Options: nosniff </ifModule>

Then you'll access in tho the app ,

I hope this can be helpfull
