Unable to connect to third party services during a build

During your build process, you may be connecting to one or more 3rd party services, such as a repository server or a remote database.

For security reasons, we restrict outbound connections from the build servers to a small number of ports, which are as follows:

TCP ports

  • 22
  • 80
  • 443
  • 3306
  • 4873
  • 5432
  • 6379
  • 9418

UDP ports

  • 53

So that DeployHQ can connect to the remote server, you'll need to ensure the protocol and connection is able to accept connections on one of those ports.
