A notification endpoint that answered with a redirect was counted as delivered: the request is not sent through a client, so the redirect is never followed, and only a status of 400 or more counted as a failure. Now any status outside 200-299 fails the delivery for ntfy, Slack and Mattermost, so it is retried and logged like the others. Model: opus-5-5
