IP Mismatch Error — How to Fix

An IP mismatch error means the IP address on your license does not match the IP your server is reporting. Here is how to fix it.

Why This Happens

Licenses are tied to your server's public IP address. An IP mismatch can occur when:

• Your server's IP address was changed by your hosting provider
• You migrated to a new server
• Your server is behind a NAT gateway or proxy that reports a different IP
• You have multiple IP addresses and the wrong one is being detected

Connect to your server and run:

curl ifconfig.me

This shows the public IP address as seen from the internet.

Log in to your dashboard, go to Licenses, and check the IP address assigned to your license.

If the IPs do not match, update your license IP:

1. Go to Licenses in your dashboard
2. Click the affected license
3. Click Change IP
4. Enter the correct IP from Step 1
5. Click Save

After updating the IP, refresh the license on your server:

66lic<ProductName>

NAT / Proxy Environments

If your server is behind a NAT gateway, load balancer, or proxy:

• The IP reported by
  Terminal

  Copy

  curl ifconfig.me

  is the one that matters — use this IP for your license
• Internal IPs (10.x.x.x, 172.16.x.x, 192.168.x.x) will not work for licensing
• If your provider rotates IPs, consider requesting a static IP
