In version 8.5, we discontinued the "Use Proxy" option for Grafana news panels. As a result, RSS feeds that are not configured for request by Grafana's frontend (with the appropriate [CORS headers](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS)) may not load.
If the RSS feed you're trying to display fails to load, consider rehosting the RSS feed or prefixing the RSS URL with your own "CORS proxy". Alternatively, you can use the community [RSS/Atom data source](https://grafana.com/grafana/plugins/volkovlabs-rss-datasource/) in combination with the [Dynamic text](https://grafana.com/grafana/plugins/marcusolsson-dynamictext-panel/) community panel to display the RSS feed.
If you're having trouble loading an RSS feed, you can try rehosting the feed on a different server or using a CORS proxy. A CORS proxy is a tool that allows you to bypass CORS restrictions by making requests to the RSS feed on your behalf. You can find more information about using CORS proxies online.
If you're unable to display an RSS feed using the News panel, you can try using the community RSS/Atom data source plugin [RSS/Atom data source](https://grafana.com/grafana/plugins/volkovlabs-rss-datasource/) in combination with the Dynamic text community panel [Dynamic text](https://grafana.com/grafana/plugins/marcusolsson-dynamictext-panel/). This will allow you to display the RSS feed in a different way.
