Hi, Team  
After upgrading from 2.26.0 to 2.27.0, the Grafana is upgraded to 8.3.5, all dashboards refuse to work.  
It complains:

```auto
origin not allowed

```

On almost every page.

Could someone help to figure out this? Thanks

I searched google and find something maybe help: [Unable to Create/Save Dashboard after v8.3.5 Update · Issue #45117 · grafana/grafana · GitHub](https://github.com/grafana/grafana/issues/45117)

But when I checked the Nginx config, I find the mentioned workaround is already there.

```auto
 # Grafana
    rewrite ^/$ $scheme://$http_host/graph/;
    rewrite ^/graph$ /graph/;
    location /graph {
      proxy_cookie_path / "/;";
      proxy_pass http://127.0.0.1:3000;
      rewrite ^/graph/(.*) /$1 break;
      proxy_read_timeout 600;
      proxy_http_version 1.1;
      proxy_set_header Connection $connection_upgrade;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Host $http_host;
    }

```

I found a way workaround for myself and you can try this:  
in your Nginx configuration file using the real domain name replace the $http\_host and restart Nginx

```auto
# proxy_set_header Host $http_host;
proxy_set_header Host example.com;

```

It worked for me, hope it can help you also.

@Luke03011 I have a small question, do you have a proxy in front of PMM? nginx or something like this?

Hi, @nikita.beletskii I Think I got you. I thought you mean the Nginx in PMM docker, but soon I realize you mean Nginx on the host running the docker. Yes, I just find there is an Nginx in front of PMM docker.

and after I add

```auto
proxy_set_header Host $http_host;

```

to the Nginx config(the host Nginx not the Nginx in the PMM docker) and reload it, It works fine. Thanks.
