hi vaulters, 

we face 1 client with readiness check failed, 

when look into cvd log at the client, there are repetitive messages

25260 5a6c 06/08 17:02:35 ### ERROR: CvFwClient::connectToGroupOfCS(): Couldn't connect to any of the CS interfaces (COMSERVER,COMSERVER)
25260 5a6c 06/08 17:02:35 ### ERROR: CvFwClient::connect(): Unable to connect to COMSERVER:8400: 0x80072747:{CQiSocket::Connect(290)/W32.10055.(An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full. (10055))}

    Hi dings,

    have the backups ever worked on this client and when was the last time it was rebooted?

    it sounds like the client is running out of ephemeral ports - https://docs.microsoft.com/en-US/troubleshoot/windows-client/networking/connect-tcp-greater-than-5000-error-wsaenobufs-10055
