Webhook connection refused from Azure DevOps

I’ve moved a repository from GitHub to DevOps, and i have changed the incoming webhook (MS calls them “ServiceHook”) to the visualstudio one.
But Bitrise apparently refuses the incoming connection from DevOps:

 An error occurred while sending the request.
    Unable to connect to the remote server
    No connection could be made because the target machine actively refused it 104.18.1.168:443

Is there some firewall settings that needs to be updated or something perhaps?
Anybody know how to solve this issue?

Thanks

Hello @chnt :wave:

Can you let me know if this issue comes up even if you create a fresh copy of your app in Bitrise, with setting Azure DevOps from the start at the time of adding an App in the WebUI? :slight_smile:

I don’t know if it does.
We have solved the issue with the help of a server-admin of the dev from my client: He needed to add a firewall-rule so the repository could contact Bitrise.
