I updated to vSphere 8 not long ago and am trying out the vCLM on one of my clusters and I am having some issues with my proxy to the inet. It seems to be connecting, but after I sync I don't seem to be downloading the newest patch, 8.0u1c (I think). I did get a fdm from July, but not sure if things are working or not.
Use the below commands from CLI to check the connectivity:
nc -zv <proxy-ip> <proxy-port> -- check proxy connectivity
nc -zv hostupdate.vmware.com 443 -- check internet/vmware connectivity
Connection timed out means it's not reachable to Internet. Need to check if any firewall/acl is blocking any IP or port. Also reconfirm that your source ip is allowed in your proxy.
Did some changes to allow http traffic along with https and now I get this when I sync the vLCM
A general system error occurred: A depot is inaccessible or has invalid contents. Make sure an official depot source is used and verify connection to the depot.
