Hi there!
If you are behind a firewall and would like to connect to App Center, here are the URLs to allowlist for App Center:
We are using the following Xamarin Test Cloud IPs. You can see the ips here:
testcloud.xamarin.com (to allow incoming/outgoing traffic on ports 80 and 443)
For our Build service, unblock the below URLs to allow our build agent to connect to your repository.
These URLs may be subject to update in the future, and we will keep our public document up-to-date for any change in the future.
We do not currently provide a list of IP addresses or ranges that you need to allowlist to connect to App Center, since these IP addresses are subject to change. If you do require IP addresses, you can use a DNS service to translate the domain names into the corresponding IP addresses.
