Note that if your instance is instance store-backed or has instance store volumes containing data, the data is lost when the instance is stopped.
Nomachine error 107 connection refused serial#
For information on configuring the EC2 Serial Console for Linux, see Configure access to the EC2 Serial Console. If your instance is unreachable and you haven’t configured access to the serial console, then follow the instructions in Method 2, 3, or 4. Also, every instance using the serial console must include at least one password-based user. Then, create AWS Identity and Access Management (IAM) policies granting access to your IAM users. You can access the serial console using the Amazon EC2 console or the AWS Command Line Interface (AWS CLI).īefore using the serial console, grant access to it at the account level. The serial console connects to your instance without the need for a working network connection.

The serial console helps you troubleshoot boot issues, network configuration, and SSH configuration issues. If you set up EC2 Serial Console for Linux, then you can use it to troubleshoot supported Nitro-based instance types. There are four methods for performing these tasks: The security group and network ACLs allow incoming traffic on TCP port 22.The SSH TCP port 22 is in the listening state.The SSH service is running on the instance.There isn't a firewall blocking the connection.If you are still having issues, send an email to help. If you take too long clicking on dialogs, the connection can timeout. The NoMachine servers allow 20 seconds to successfully authenticate. One possibility is that the connection timed out. When logging in, I get a dialog box that says "Connection error". Why can't I connect?Ĭlick the Detail button to see a more detailed message.You should then get prompted to accept the new key which has the RSA fingerprint 78:6f:5e:70:0b:1e:57:27:f2:7b:74:c7:84:f1:3a:19. In both cases, delete the first line and then reconnect.

In the second example (from a Mac), the offending key is stored on line 1 of /Users/username/.ssh/known_hosts.
Nomachine error 107 connection refused windows 7#
In the first example (from a Windows 7 machine), the offending key is stored on line 1 of C:\Users\username\.ssh\known_hosts. The solution is to remove the offending key from the known_hosts file. Because you had previously connected, the old key was stored on your computer. In January 2011, we updated the RSA host keys for the NoMachine servers.
