The error message "kex_exchange_identification: read: Connection reset" typically occurs when there is a problem with the SSH connection. Here are a few possible causes and solutions for this issue:
-
Network Issue: The connection reset error can occur due to a drop in the network connection. Check your internet connection and ensure that it is stable. You can also try connecting from a different network to see if the issue persists.
-
Firewall/Router Configuration: Some firewalls or routers may be blocking the SSH connection. Check the settings of your firewall or router and make sure they allow SSH traffic.
-
SSH Configuration: Incorrect SSH configuration settings can also cause this error. Make sure that the SSH server is properly configured and running on the remote machine you are trying to connect to.
-
SSH Version Compatibility: In some cases, the SSH client and server versions may not be compatible. Ensure that you are using compatible versions of SSH client and server software.
-
VPN Connection: If you are using a VPN, try disconnecting from the VPN and then reconnecting to see if the error persists. Sometimes VPNs can interfere with SSH connections.
If none of these solutions work, it is recommended to seek further assistance from your network administrator or the support team of the system you are trying to connect to.
