Hi
I am trying to connect to my ESXi server from my laptop using (vmware view open client) but it gives me an error msg that I have to check the server address,port,network and SSL settings !!..the connection is ok and I can ping the ESXi server from the terminal but I can't get into it through any vmware or RDP viewer !!
I have attached a screenshot of the error

Thanks
