Hi @allegator,
The error 403
means that the RSS server is prohibiting/blocked access to the RSS feed.
It could be some configuration issue or a mistake. If possible, please check with the feed owner if there are any specific restrictions placed.
An alternate would be to create a proxy for the RSS feed using feedburner – https://feedburner.google.com/
Enter the RSS feed URL and copy the feedburner URL. That should help resolve this issue.
Thanks,
Aakash
