Too many open ports from grafana

[anon70503803]

What version of Grafana. We had a breaking change with our reverse proxy rules in 8.3.6:

Origin not allowed messages after upgrade to 8.3.6

In the case of Apache Server, you need to add ProxyPreserveHost on in your proxy configuration. In case of NGINX, you can need to add proxy_set_header Host $http_host; in your configuration. It is broken for IPv6 access: https://github.com/grafana/grafana/issues/45115
