I am using vcenter version 6.0. VCenter installed as a server appliance on OS SUSE Linux Enterprise 11.
I'm having trouble not able to connect to vCenter from vSphere
Server error: 503 Server Unavailable
What do I need to do to remedy the above situation
If you have any idea about fixing this, please help me.
Which vCenter version do you use?
Note that the "old" Windows based vShphere client does not work with current versions anymore, and has been replaced with the web based (vCenter Server integrated) client.
connect to vcenter by ssh and check the services: ( the next command was runned on a vcsa 6.5)
applmgmt lwsmd pschealth vmafdd vmcad vmdird vmdnsd vmonapi vmware-cis-license vmware-cm vmware-content-library vmware-eam vmware-perfcharts vmware-psc-client vmware-rhttpproxy vmware-sca vmware-sps vmware-statsmonitor vmware-sts-idmd vmware-stsd vmware-updatemgr vmware-vapi-endpoint vmware-vmon vmware-vpostgres vmware-vpxd vmware-vpxd-svcs vmware-vsan-health vmware-vsm vsphere-client vsphere-ui
vmcam vmware-imagebuilder vmware-mbcs vmware-netdumper vmware-rbd-watchdog vmware-vcha
tell us what the command shows,
If you are running anything like production workloads in that vSphere environment, you should consider upgrading (vCenter Server and ESXi hosts) to at least 6.5 to be on a version which is still supported and updated.
Although the error message is slightly different to the one that usually show up in case of expired certificates, I'd still uggest that you run the commands in section "Reviewing stored certificates for vCenter Server Appliance:", step 3 from https://kb.vmware.com/s/article/2111411 to check whether the certificates have expired.
@leduc28 It looks like the vmware-vpxd next to a couple other important services are not running. So it makes sense you cannot connect to the vCenter Server.
Can you have a look in the vpxd.log file as to why the service is not running?
invsvc, vapi, vpxd down. Could be a solution user cert issue.
Run service-control --start --all and post the output of the service log that fails.
