Unsure why but I see this message alot in the Horizon 7 error log yet the password still works for me to get into the vsphere client. When I try to go to the url (https://url:443/sdk) it provides an error on unknown site. Horizon details state service is not working and certificate is untrusted but thumprint for certificate is accepted. Horizon VM is talking and seems to be working with the vCenter Server appliance with no error when I bring open screens.
