After updating to version 6.2, Grafana stopped displaying charts embedded on another page.
Wordrpess, which I use, adds “amp;” or “#038” to links in the iframe and the query is not recognizable by the Grafana. Earlier versions of such a problem did not have.
Any idea how to fix it?
Solution:
we are opening the file: /etc/nginx/sites-available/twojastrona.com
in the server section we add proxy_hide_header X-Frame-Options;
we restart nginx. From now everything should work.
