Resolving WinError 10060 Connecting SFTP to Azure VM
In this article, we will discuss how to resolve the WinError 10060 that occurs when connecting to an SFTP site from a Python script running on an Azure VM. This issue can be frustrating, but with the right information, it can be easily resolved.
Understanding WinError 10060
WinError 10060 is a Windows error that occurs when a connection attempt to a remote server fails due to a timeout. This error can occur when connecting to an SFTP site from a Python script running on an Azure VM due to several reasons, including network connectivity issues, firewall settings, and authentication problems.
Troubleshooting Network Connectivity Issues
The first step in resolving WinError 10060 is to troubleshoot network connectivity issues. This can be done by checking the network settings on the Azure VM and ensuring that the VM can connect to the internet. You can also use tools like ping and traceroute to diagnose network connectivity issues.
ping <SFTP site>
traceroute <SFTP site>
Checking Firewall Settings
Firewall settings can also cause WinError 10060 when connecting to an SFTP site from a Python script running on an Azure VM. You need to ensure that the firewall on the Azure VM is configured to allow incoming traffic on the SFTP port (default is 22). You can check the firewall settings by running the following command:
netsh advfirewall firewall show rule name="SFTP-In"
If the rule does not exist, you can create it by running the following command:
netsh advfirewall firewall add rule name="SFTP-In" dir=in action=allow protocol=TCP localport=22
Configuring Authentication Settings
Authentication problems can also cause WinError 10060 when connecting to an SFTP site from a Python script running on an Azure VM. You need to ensure that the authentication settings in your Python script are correct. This includes the username, password, and private key (if using key-based authentication).
import paramiko
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
username = 'your_username'
password = 'your_password'
host = 'your_SFTP_site'
port = 22
ssh.connect(host, port, username, password)
sftp = ssh.open_sftp()
# Perform SFTP operations here
sftp.close()
ssh.close()
