Autobuild Not Triggering

I have autobuilds setup for my linked GitHub repository and it has been working fine until about 2 weeks ago. Now when I create a release in GitHub, autobuild isn’t being triggered any longer. When I check the Webhook settings in my GitHub repository, I can see that Docker Hub is responding with a 202, yet autobuild isn’t being triggered:

Is there anything to check on the Docker Hub side? I can’t find any logging…
