Update vardot.com on Planet Drupal

The feed does not pass validation.

line 456, column 61: guid values must not be duplicated within a feed: 10234 at https://www.vardot.com

It's likely a cached version.
New URL: https://www.vardot.com/en/rss/planet.xml

Thank you

Now, the error show by the validator is the following one.

Server returned HTTP Error 404: Not Found

I get Congratulations! for the same URL. Can you try again please?

I tried with a different validator, but I get a different error.

It looks like this is a web page, not a feed. I looked for a feed associated with this page, but couldn't find one. Please enter the address of your feed to validate.

The same error has been shown by FEED Validator

Strange.
I get "Congratulations This is a valid RSS feed" even from FEED Validator.

Are you sure you are using https://www.vardot.com/en/rss/planet.xml?

Yes, I am.

Clearly you are not.
The URL in the bar in the screenshot is https://www.vardot.com/en/rss/drupal-planet.xml
While I'm asking you to confirm using https://www.vardot.com/en/rss/planet.xml

Am I missing something or are you missing something?

I apologize: I take the URL from the issue summary, since it is earlier to get. I did not notice the comment shown a different URL.

No worries, it happens.
I hope the new URL works.

The feed passed validation, and it contains at least two feeds.

I added the feed to Planet Drupal ( https://www.drupal.org/aggregator/sources/2096 → ).
