## IPs in Whitelist are failing to connect
## IP addresses in whitelist are failing to connect
If you're unable to connect from IPs in your IP Whitelist, check if you are running n8n behind a reverse proxy.
If you're unable to connect from IP addresses in your IP whitelist, check if you are running n8n behind a reverse proxy.
If so, set the `N8N_PROXY_HOPS` [environment variable](/hosting/configuration/environment-variables/index.md) to the number of reverse-proxies n8n is running behind.
## Only one webhook per path and method
n8n only permits registering one webhook for each path and HTTP method combination (for example, a `GET` request for `/my-request`). This avoids ambiguity over which webhook should receive requests.
If you receive a message that the path and method you chose are already in use, you can either:
* Deactivate the workflow with the conflicting webhook.
* Change the webhook path and/or method for one of the conflicting webhooks.
