Error origin not allowed

I have grafana configured with two internal and external urls.

Internally everything works correctly and externally too, I have updated to 8.4.0 and I find that externally I get the error origin not allowed

I have added in nginx and it has been fixed for internal.
location / {
proxy_pass http://localhost:3000/;
proxy_set_header Host $http_host;
}

But it still doesn’t work externally.

what version were you running before the upgrade?

I have running 8.4.0 before update have 7.1

Javascript is limited by the "same origin policy for security reasons so that a malicious script cannot contact space bar clicker a remote server and send … You can just put the Header set Access-Control-Allow-Origin setting in the Apache configuration or htaccess file . It should be noted that this effectively disables CORS protection, which very likely exposes your users to attack.
