Patreon unable to emit webhook using URL

I have my webhook set up on http://ip:3000/patreonwebhook
I have a subdomain pointing to this called

When I try to test my webhook I get the error:
Test Response

Error: _HTTPSConnectionPool(host=‘’, port=443): Max retries exceeded with url: / (Caused by NewConnectionError(’< object at 0x7f55dee23b50>: Failed to establish a new connection: [Errno -2] Name or service not known’))

Your subdomain doesnt seem resolvable it seems. You can try with a domain or subdomain which resolves.
