Incorrect URL validation about healthchecks HOT 2 CLOSED

I've now fixed the URL validation code to allow URLs with just hostname and no domain or tld. http://ntfy/healthcheck should work now.

I did not tie the URL validation logic to the INTEGRATIONS_ALLOW_PRIVATE_IPS setting, because private IPs and "naked hostnames" are not the same thing:

• A normal-looking URL can resolve to a private IP: example.org A 192.168.0.1.
• And, conversely, when using a private DNS, a "naked hostname" can resolve to a public IP: ntfy A 1.2.3.4

from healthchecks.

Thanks for the report.

We have the INTEGRATIONS_ALLOW_PRIVATE_IPS setting. It this setting is enabled, it would make sense to also relax URL validation rules. I'll see what can be done here.

In the meantime, as a workaround, you can use the IP address instead of the hostname in the URL.
