Launching webhooks fails with "Unacceptable URL" no matter how simple the webhook configuration is.
FogBugz On-Premises has a built-in local traffic detection mechanism to prevent webhooks from hitting sites in the internal network. The intent behind this is to prevent external users from making FogBugz a jumping-off point to explore the local network.
Usually, this feature is not viewed as a limitation because users already have access to internal networks.
- Administrator role in FogBugz
FogBugz On-Premises will reject as "Unacceptable URL" any webhook requests targeting hosts having the following IP addresses or domains:
- all IPv6 addresses
127.0.0.0/8IPv4 ranges (class A private network)
- the following domains:
Use class C private network
192.168.0.0/16 (class C private network) range is allowed by the local traffic detection mechanism. If your webhooks try to access hosts having IP addresses from this range, FogBugz On-Premises will execute the requests.
