Inconsistent snap build webhook trigger result for the gallery-dl snap

Hello, I’ve been notified that the gallery-dl snap has recently encountered an issue with inconsistent snap build webhook trigger results, where in some push events, the request returns a 404 error.

Please check the status of the integration webhook in the Webhooks section of the repository’s settings page.

Same issues as in #7841 (comment), but I’ve renewed the Webhook. It even worked for a git push and triggered an automatic build 24h ago, which according to https://github.com/mikf/gallery-dl/settings/hooks/254582030?tab=deliveries also failed with a 404 error.

Refer to the following links for the details of the failed webhook triggers:
