I have a RSS web part in SharePoint 2016 that suddenly not displaying the feed correctly.

RSS error

The error I found in the ULS log is "The request was aborted. Could not create SSL/TLS secure channel"

SSL error ULS

I have already added the SSL cert, the intermediate and root cert of the news site to the SharePoint trust and server trust folder.

I have verified that it's a legit URL feed that works on SharePoint Online, but not on this SP2016.

Please advise on what else I need to do.

First and foremost, check the permissions of the account that is reading the RSS source. If the permissions have changed, you have an AuthZ issue.

If the account reading the source has the requisite permissions to read the data source, you are dealing with an AuthN issue, likely caused by a changed or expired password.
