XF 2.2 RSS feed issue

[Thunderfall]

Has there any change to Xenforo RSS feed recently? On my main site WordPress page, I have an RSS widget that uses below as source URL:

https://forums.{MySite}.com/forums/-/index.rss

Recently this stopped working and below error is shown:

Recent Forum Posts
RSS Error: WP HTTP Error: A valid URL was not provided.

Any idea?

I replied to your ticket.

Nothing has changed in XF.

If you open that URL in a browser you will see that is a valid rss feed.

Issue resolved now.
