How to fix Error: timeout - last error: dial tcp: i/o timeout in Terraform

# Test with curl (for HTTP/HTTPS endpoints)
curl -v https://api.example.com:443

# Test with nc (netcat) for TCP connectivity
nc -zv 54.89.109.252 22

# Test with timeout to prevent hanging
timeout 5 bash -c '</dev/tcp/54.89.109.252/22' && echo "Connected" || echo "Connection failed"

# Set environment variables before running Terraform
export HTTP_PROXY=http://proxy.example.com:8080
export HTTPS_PROXY=http://proxy.example.com:8080
export NO_PROXY=localhost,127.0.0.1,internal.example.com

# Or in PowerShell on Windows
$env:HTTP_PROXY = "http://proxy.example.com:8080"
$env:HTTPS_PROXY = "http://proxy.example.com:8080"

# Then run Terraform
terraform plan

echo 'export HTTPS_PROXY=http://proxy.example.com:8080' >> ~/.bashrc
source ~/.bashrc
