I believe this error is coming while you are trying to import the port binding in BizTalk.
There can be following two reasons for this type of failure:
1) The host name in binding file does not match any of the hosts in BizTalk Server. Hence the binding is unable to attach a host to your artefact and it failed.
2) The trust level of the host in binding file does not match the host's in BizTalk Server.
Most of the time its pt no. 1 as there are multiple environments with different host names. So, there are chances of host name mismatch when we import a different environment's config by accident.
To manage deployments, I suggest using BTDF https://biztalkdeployment.codeplex.com/
] it handles deployments and is pretty awsome to use !!!
