Background<\/h2>\n\n\n\n

So recently I was updating my homelab with ESX 7.0 and a brand spanking new vCenter install. I choose to completely wipe my old homelab on the ESX environment and completely reinstall it. <\/p>\n\n\n\n

I started with the ESX installation through this manual (https:\/\/kb.vmware.com\/s\/article\/2004784<\/a>) and deployed a domain controller on the new VMware host.<\/p>\n\n\n\n

So when the domain controller was up and running and all was well I started deploying the vCenter appliance using this manual (http:\/\/arnaudpain.com\/2020\/05\/26\/vmware-vcenter-7-0-install-step-by-step\/#sthash.Zk3q8m3p.dpbs<\/a>).<\/p>\n\n\n\n

Problem<\/h2>\n\n\n\n

This worked and now I wanted to configure the vCenter. so browsed to the site.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

After starting the HTML5 client I got this error:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Troubleshooting tips<\/h2>\n\n\n\n

Trying to figure out what was wrong I logged on the administration site and checked if all services where running you can do this with the following steps<\/p>\n\n\n\n

1.log in https:\/\/VCFQDN:5480<\/a>   check if the services VMware vCenter Server , an VMware vSphere Client are running<\/p>\n\n\n\n

2. if VMware vSphere Client service can not start , check the var\/log\/vmware\/vsphere-ui\/logs\/*runtime.log.stderr<\/strong> logfile<\/p>\n\n\n\n

It could also be a problem with the SSL certificate expiring, then the STS service will probably fail. \\sso check the certificates (which is always a good tip :-))!<\/p>\n\n\n\n

Otherwise there could be a problem with free diskspace on the vCenter appliance, you can check that by connecting via SSH to the vCenter appliance and pasting this command: (after getting shell access)<\/p>\n\n\n\n

hostname -f && date && uptime && vpxd -vl && chage -l root && df -h && service-control –status.<\/strong> <\/p>\n\n\n\n

It should give enough room on all volumes e.g. like this screenshot. If one of the disks is full it will give 100% in use. then you need to enlarge the disk (or figure out why it’s full ;-))<\/p>\n\n\n\n

Solution<\/h2>\n\n\n\n

After some searching online and checking with one of the vExperts (@laurensvanduijn<\/a> thanks for the tip!) it was (as always) DNS. Before configuring the vCenter applicance you need a valid DNS record for the vCenter pointing to the correct IP adress (which i had).<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

<\/p>\n\n\n\n

And a valid PTR record in DNS for the vCenter appliance (which i didn’t have). <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

These things need to be in place BEFORE<\/strong> deploying the vCenter appliance, adding them afterwards didn’t solve my issue. So after creating the PTR record in DNS and redeploying the vCenter appliance. It started working as expected!<\/p>\n\n\n\n
