After upgrading to 8.3.5, all dashboard boards are refusing to work

  • What Grafana version and what operating system are you using?
    8.3.5, and the Grafana is begind a Ngnix

  • What happened?
    after upgrading from a 7.x version to 8.3.5, all dashboards are refusing to work, almost all of the pages are complaining: origin not allowed.

  • What did you expect to happen?
    dashboards work as before

I searched the internet, there are many tickets about this, and some of them give a workaround by adding

proxy_set_header Host $http_host;

the Ngnix conf:

server {
    listen 80;
    listen 443 ssl http2;
    server_name _;
    server_tokens off;
   location /auth_request {

      auth_request off;

      proxy_pass http://managed-json/auth_request;

      # nginx always strips body from authentication subrequests.
      # Overwrite Content-Length to avoid problems on Go side and to keep connection alive.
      proxy_pass_request_body off;
      proxy_set_header Content-Length 0;

      proxy_http_version 1.1;
      proxy_set_header Connection "";

      # This header is set only for to the second request, not for the first subrequest.
      # That variable is set above.
      proxy_set_header X-Must-Setup $auth_request_must_setup;

      # Those headers are set for both subrequest and normal request.
      proxy_set_header X-Original-Uri $request_uri;
      proxy_set_header X-Original-Method $request_method;
# Grafana
    rewrite ^/$ $scheme://$http_host/graph/;
    rewrite ^/graph$ /graph/;
    location /graph {
      proxy_cookie_path / "/;";
      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;

But still no luck, I also saw many people saying the same situation.

Could someone help with this? Thanks in advance.

I find there is an extra Nginx, the following config does solve the issue.

 proxy_set_header Host $http_host;
