Cannot access vCenter anymore after disk space issue

Hi,
I am using vCenter ESXi 6.0.
Since I ran out of space on VCSA due to very big audit.log file, I followed this URL:
https://kb.vmware.com/s/article/2149278

I changed root password, and rebooted vCenter Appliance.
I am unable to access through vcsa.
In web interface, I get error:

503 Service Unavailable (Failed to connect to endpoint: [N7Vmacore4Http20NamedPipeServiceSpecE:0x7f9ab7e2ac40] _serverNamespace = / _isRedirect = false _pipeName =/var/run/vmware/vpxd-webserver-pipe)

Even with vSphere client (the server could not interpret client's request)

How can I solve this?
Thank you

Did you expand the disks ?

anyway, I just removed an 8 GB audit.log file.
I noticed something strange.
I used vSphere to access the host on which vcsa is running, it shows me a 200 GB hard disk.
I don't see such space in df -h output..

so I used /usr/lib/vmware-vmdir/bin/vdcadmintool and reset credentials (option 3).
After vcsa reboot, all went fine.
