Resolution
1. If proxy is used in vcenter, please check the connectivity using wget command:
wget --no-check-certificate https://<vcenter_IP>:443/omevv/VcenterService/plugin.zip
2. Try to remove the omevv plugin from vcenter using MOB page and try registering using DELL open manage integration.
3. Check the firewall rules between proxy server/vcenter and DELL open manage and verify all ports are open as per above mentioned document.
4. Some version of omevv plugin like 1.4.X doesn't support TLS 1.3 in Open manage integration. Check TLS is configured to use 1.2 or earlier in Open manage side.
Check Dell documentation on version of plugin you are using for more information and to know issues with it.
