Could not connect to one or more VCenter

I am running the vsphere 6.5 vcenter appliance. It is the only vcenter server we have. I can connect to it through the webclient, I can log in but it does not show me any inventory

As can be seen, only shows Could not connect to one or more VCenter Server. I already tried KB2050273. But is not my case.

I checked the services

I tried to start vmware-vpxd service but never started.

I checked the space and seems to be ok

This is part of the vpxd.log | grep -i "error"

This vcenter appliance used to work. But it has had this problem two weeks ago.

Any ideas on how to get this VCSA to manage the environment again?

Thanks
