Trying to pscp a pem file from windows machine to Brocade adx 1000

Brand new to Brocade or any switch, I managed to configure load balancing without ssl and now working on ssl enabling. I have a PEM file on my IIS server and I try to copy this to the switch using pscp bond.pem admin@x.x.x.x:sslcert:jackash:pem pscp -scp bond.pem admin@x.x.x.x:sslcert:jackash:pem I get the error - The first key-exchange algorithm supported by the server is diffie-hellman-group1-sha1, which is below the configured warning threshold. Continue with connection? (y/n) y bond.pem | 3 kB | 3.4 kB/s | ETA: 00:00:00 | 100% FATAL ERROR: Received unexpected end-of-file from server I have enabled scp on brocade. What am I doing wrong here?
