/var/log/vmware/vpxd/hsm-service.log displays repetitive connection failures and proxy errors when attempting to reach the HSM host:HTTPSConnectionPool(host='################.###.##########.net', port=443): Max retries exceeded with url: /omevv/GatewayService/v1/vsphere-lcm/hw-support/v1/packages (Caused by ProxyError('Your proxy appears to only use HTTP and not HTTPS, try changing your proxy URL to be HTTP. See: https://urllib3.readthedocs.io/en/1.26.x/advanced-usage.html#https-proxy-error-http-proxy', SSLError(SSLError(1, '[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1007)'))))., start retrying list_packages for 5 times with interval: 5vCenter: 8.0 U3g

The issue occurred because the HSM IP address and FQDN were mistakenly added to the proxy configuration in VAMI (vCenter Server Appliance Management Interface) under "Networking > Edit Proxy Settings". As a result, hsm-service was unable to establish proper communication with the Hardware Support Manager until the incorrect proxy configuration was corrected.
Steps to Follow to Resolve the Issue:
service-control --stop --all && service-control --start --all
