SharePoint Asked on December 10, 2021
In Dec 2017 RSS viewer webpart was working fine, In Jan 2018 new patches from Microsoft were installed on SharePoint server after that it is giving error in RSS Viewer Webpart
The requested RSS feed could not be displayed. Please verify the settings and url for this feed. If this problem persists, please contact your administrator
When I checked the ULS logs I found out two below exceptions:
