The Grid won't load RSS feed

[marketfresh]

Hello, I’m trying to load this RSS feed into The Grid: https://blog.traillifeusa.com/rss.xml
But I’m getting this error:
“Sorry, an error occurred while retrieving RSS content: WP HTTP Error: A valid URL was not provided.”

I validated the RSS feed here: https://validator.w3.org/feed/check.cgi?url=https%3A%2F%2Fblog.traillifeusa.com%2Frss.xml

Hello Jonathan,

Thanks for writing in!

I have used your feed and set up a grid in my local testing server. I could not replicate any issue. The grid is displaying on my end.

Please make sure that you have set up your grid properly. This is how I set my own grid:

Hope this helps.

I’m doing the same thing and it doesn’t work for me.
What else could be causing the problem?

Update,
I tried the same RSS url in the Grid on a different site and it worked fine.

I also tried the RSS feed in a different plugin on a stage.traillifeusa.com and it DIDN’T work there. Also tried it with all plugins (except the Grid) disabled and it didn’t work.

I’m wondering if there is a problem with loading an RSS feed from a subdomain? I’m really stuck here.

Hi Jonathan,

That seems to be a server security-related issue, please follow the solution given on the link below.
