My Theme Support RSS feeds not working

Just a while ago, my email client is no longer importing the feeds from each of my free themes here at www.ads-software.com. Here is an example of the feeds I entered for my RSS imports per theme:

https://www.ads-software.com/support/theme/unblock/feed

It’s a 404, as is with my other ones. I did come across a 6-month-old posting HERE but the link(s) is 404.

Has something recently changed as it relates to getting a feed for the support forums for free themes? I’ve had this set up for notifications when someone posts in either one.
