We have support server where would need to upload the snap data to IBM using proxy connection. We have already whitelisted the Server IP Address on the proxy side, Tried the ssh -J proxyjump option getting connection closed error. ssh_exchange_identification: Connection closed by remote host.

Server IP:

Proxy Server Details: port: 8080

IBM SFTP Server Details: sftp.ecurep.ibm.com Port: 22

  • Is this a HTTP proxy? -J is for "middle" SSH servers ("jump hosts"), not for HTTP proxies Dec 23, 2018 at 20:57
