Unable to load the vSphere Web Client

Hi,

'm facing the very common error when navigating to the vSphere Web client -

503 Service Unavailable (Failed to connect to endpoint: [N7Vmacore4Http20NamedPipeServiceSpecE:0x7f0cb4715570] _serverNamespace = / _isRedirect = false _pipeName =/var/run/vmware/vpxd-webserver-pipe)

I've searched a lot and tried a variety of solutions but none of them are working.

The main issue is the Web Client service is stopped, and upon starting this manually, it stops again in a bit. I've restarted the appliance several times but it has not helped.

Running on VCSA 6.0 with external PSC.
