Could you please confirm whether you are trying to connect to Dev Cloud.
I can see that you are connecting to the DevCloud.
You might want to check the RSA public key to see if it is corrupted. If not please talk to Shanghai Intel IT to see if the proxy is set correctly.
I'm in JF and the following works, it is probably different for Shanghai
ProxyCommand nc -X 5 -x proxy.jf.intel.com %h %p
Change your network source and try connecting again . It worked for me because mine was collage network and it was blocking me from connecting to cluster . Hope this helps .
Thanks, problem has been fixed when using sed network.
