Known issue from previous VCSA installations. I have had something with vSphere 6.7 but in a nested environment.
Still check your IPs and FQDN. Subnet, Gateway, DNS once again.
Please check logs on your PC (jump host) used for deploing VCSA: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vcenter.install.doc/GUID-D2E655AE-A1B2-4727...
If you cannot find any errors in logs you can redeploy vm using new copy of VCSA ISO file.
