When you are happily using vCenter6.5 to manage your beloved data center, the following screen suddenly appears on the interface at some point:

503 Service Unavailable (Failed to connect to endpoint: [N7Vmacore4Http20NamedPipeServiceSpecE:0x7f0782fb55f0] _ serverNamespace = / _ isRedirect = false _ pipeName = / var/run/vmware/vpxd-webserver-pipe)

And at the same time, restarting vCenter won't work anyway. At this point, please do not panic, just follow these steps, the problem can be easily solved, and all the data in the data center is intact:

1. Log in to the vCenter Applience virtual machine using ssh or directly from the ESXi interface and enter SHELL Last login: Thu Sep 28 10:05:40 2017 from 10.4.143.97 Connected to service * List APIs: "help api list" * List Plugins: "help pi list" * Launch BASH: "shell" Command > shell Shell access is granted to root 2. Enter the following command: service-control-- status vmware-vpxd sees the status as "Stopped" 3. Enter the following command: service-control-- start vmware-vpxd does not start the service

After confirming 2pm and 3pm, continue with the execution:

4. Enter the following command: / opt/vmware/vpostgres/current/bin/psql-d VCDB-U postgres, which logs in to postgres database 5. Enter the following command to find the virtual machine in question: select v.id, v.local_file_name, h.IP_ADDRESS FROM VPX_VM v, VPX_NIC n, VPX_HOST h WHERE v.id=n.entity_id and v.host_id=h.id and n.networknamed virtual machines; 6. Enter the following command to replace the "" of this statement with the virtual machine id obtained in 5: select * from vpx_entity where id ='; 7. After finding the affected virtual machine, you have two options: 1) delete the corresponding virtual machine and delete the corresponding record: delete from vpx_entity where id =''; 2) delete the virtual machine's network adapter (Network Adepter)-> Save-> add the network adapter 8. Enter the following command: service-control-- start vmware-vpxd you will see that your vCenter is accessible.

The affected vCenter version is Version 6.5.0 Build 4944578 because the Nic data item null (NULL) value appeared in the virtual machine database when the virtual machine was created.
