When connecting to a Raspberry Pi, the "Software caused connection abort" error in PuTTY occurs. This error often indicates disturbance in the communication between your computer and the Raspberry Pi, leading to an unexpected termination of the connection.
We provide the common causes and provide other options to help you determine and solve the connection abort problem, ensuring an easy and stable connection to your Raspberry Pi.
The "Software caused connection abort" error in PuTTY when connecting to a Raspberry Pi can be caused by various factors.
Also check using cryptographic key for authentication on Cisco device.
Here are some common reasons and solutions:
Network Issues:
Check your computer and the Raspberry Pi network connections. Make sure that both devices are on the same network and that there are no network disturbances.
Firewall Configuration:
Verify your computer and the Raspberry Pi firewall settings. Check that the SSH port is allowed through the firewall.
Incorrect IP Address:
Confirm that you are connecting to the Raspberry Pi using the correct IP address. Running the command hostname -I on the Raspberry Pi will display the IP address.
Insufficient Raspberry Pi storage
Check that the Raspberry Pi has enough storage to handle the SSH connection. Consider optimizing or upgrading the Raspberry Pi if its capacity is insufficient.
PuTTY Configuration Issues:
Review the PuTTY configuration. Check that the correct settings, such as the IP address, port, and connection type (SSH), are configured.
Antivirus Safety:
Some anti-virus and security applications can trigger SSH connections to be unsuccessful. Disable or modify the settings of any such program temporarily to see if it resolves the problem.
By checking all these issues, you can resolve the Software caused connection abort error when connecting to Raspberry Pi from PuTTY. Now you can successfully connect to Raspberry Pi to manage the function.
