Could not integrate the ESXi host in to vCenter server.

Issue:-Could not integrate the esxi host in to vCenter server.

vCenter version :- 6.5 and ESXi version:- 5.5.0 U3

Error in vCenter while connecting the ESXi host:- A general system error has occurred: Timed out waiting for vpxa to start".

ESXi host error:- VPXA service got stopped after 19 seconds(whenever we restart the VPXA service).There was no VPXA log recorded in VPXA.log.All were the year 2018 logs only.

In addition,we found this error in cat /var/log/syslog.log  error  "/etc/vmware/vpxa' exited after 19 seconds (quick failure 1) 134"

    <serverIp>VC private IP address</serverIp>

    <serverPort>902</serverPort>

  </vpxa>  

Steps followed to resolve this issue:-

1st step:-Taken ESXi reboot but not resolved this issue.

2nd step:- We removed the / from <serverIP> & <serverPort> in the beginning and taken vpxa start.It resolved the issue without ESXi reboot.

Note:- Previoulsy it was  <serverIP/> & <serverPort>

Now the ESXi server got integrated in to vCenter server and vpxa service is stable.

Happy learning!
