There was a cephadm bug that wasn't fixed by the time 17.2.6 came out (I'm assuming that's the version being used here, although it may have been present in some slightly earlier quincy versions) that caused this misleading error to be printed out when adding a host failed. There's a tracker for it here https://tracker.ceph.com/issues/59081 that has roughly the same traceback. The real issue is likely a connectivity or permission issue from the active mgr trying to ssh to the host. In the case I saw from the tracker, it was caused by the ssh pub key not being set up on the host. If you check the cephadm cluster logs ("ceph log last 50 debug cephadm") after trying to add the host I'm guessing you'll see some error like the second set of output in the tracker that will hopefully give some more info on why adding the host failed.
