Troubleshooting

# Step 1: Test basic connectivity
curl -v -x http://basic.resi.zentislabs.com:12321 \
  -U "USERNAME:YOUR_PASSWORD_country-us" \
  https://httpbin.org/ip

# Step 2: Test with timeout
curl --connect-timeout 10 --max-time 30 \
  -x http://basic.resi.zentislabs.com:12321 \
  -U "USERNAME:YOUR_PASSWORD_country-us" \
  https://httpbin.org/ip

# Step 3: Check DNS resolution
nslookup basic.resi.zentislabs.com

# Step 4: Test port connectivity
# Windows:
Test-NetConnection basic.resi.zentislabs.com -Port 12321
# Linux/macOS:
nc -zv basic.resi.zentislabs.com 12321
