The previous SSL certificate of
hooks.bitrise.io (webhook server) will expire early next month, so we went ahead and updated it with a new one.
This should not cause any issues, but it seems it might in some rare cases.
If you’d see a build not triggering on GitHub.com, please check the Repository Settings → Webhooks → select the
hooks.bitrise.io one → and search for the failed webhook in the Recent Deliveries list.
If you see a webhook with a Response:
We had a problem connecting to the server. The most common problem with these types of errors is a misconfigured SSL certificate. Try verifying your certificate chain.
Simply click Redeliver and it will work.
