Hi, I'm using this nix docker to build other dockers in gitlab CI, but it's failing to run the servant test suite because of errors like the following:
(ConnectionFailure Network.Socket.getAddrInfo (called with preferred socket type/protocol:
AddrInfo {addrFlags = [AI_ADDRCONFIG], addrFamily = AF_UNSPEC, addrSocketType = Stream,
addrProtocol = 0, addrAddress = <assumed to be undefined>, addrCanonName = <assumed to be undefined>},
host name: Just "localhost", service name: Just "34263"): does not exist (Name or service not known)))
