Hi, I am trying to use Webhook integration but I am getting an ‘unknown host’ error when I put the Webhook url (BitBucket url). Is there any recommended solution to this? Last one, I was trying use DT problem as a plan build trigger on Bamboo, read that the in order to trigger the build a remote trigger from Bamboo should be enabled which I was doing but it needs an IP from source which is DT on this point. We are using Saas, I am stuck on the IP or CIDRs. ---

Hi [@Itani\_ML](https://community.dynatrace.com/user/70129) , When you are getting an ‘unknown host’ error, is there any other information that you can provide other than this error message? Furthermore, are you also receiving this in the logs? A more detailed description of what might be happening could potentially have hints here. In addition, if you need additional help on this, depending on how detailed the logs are, you may also want to consider opening a Support Ticket and providing the logs for greater analysis: > **[Home | Dynatrace Support Portal](https://support.dynatrace.com/)** ---

Hi [@Itani\_ML](https://community.dynatrace.com/user/70129) Can you check that your BitBucket instance allows the IPs from your Dynatrace SaaS solution to receiving the incoming payload? I’ve seen unknown host where i am unable to send out notifications due to FW or IP whitel\*sting missing. Our Alerting IPs are here - [Additional IP addresses for public alert notifications (customer action required)](https://www.dynatrace.com/news/blog/additional-ip-addresses-for-public-alert-notifications-customer-action-required/) Thanks, Lawrence ---

Hi, I get the error when configuring the HTTP url ![Itani_ML_0-1704914697193.png](https://global.discourse-cdn.com/dynatrace/original/3X/0/e/0e119354edbc1fc3cf7ec3c3c9884f9bb06f5b3b.png) ---

Hi [@Itani\_ML](https://community.dynatrace.com/user/70129) Have you checked bitbucket can receive requests from public networks such as Dynatrace? Thanks, Lawrence ---

Hi, yes. It does take requests. So the error is in DT but on this one I was trying with Bamboo ![Itani_ML_0-1704914697193.png](https://global.discourse-cdn.com/dynatrace/original/3X/0/e/0e119354edbc1fc3cf7ec3c3c9884f9bb06f5b3b.png) ---

[@Itani\_ML](https://community.dynatrace.com/user/70129) Okay, I am assuming that the destination is a local host? Example: [https://myhost1:8443/rest/api/](https://myhost1:8443/rest/api/)\*\*\*\*\*\*\* If the host is internal, Dynatrace won’t be able to see it publicly so we throw the error “Unknown Host”. I suggest looking at this blog [IP Addresses for Notifications](https://www.dynatrace.com/news/blog/additional-ip-addresses-for-public-alert-notifications-customer-action-required/) for starters The endpoint Dynatrace is connecting to needs to allow public communication to our SaaS endpoints above, so we can see it as available. Can you confirm? 🙂 Thanks, Lawrence ---

Hi, yes you are right. Thanks for the help.
