Many users encounter various errors when upgrading to ChatGPT Plus, especially related to credit card verification and payment callback issues. This article breaks down the most common subscription error codes and provides step-by-step troubleshooting steps to help you get upgraded fast.
Error Code: card_declined – Credit Card Declined
This is the most common subscription failure, usually showing “Your card was declined.” First, make sure your card supports international online transactions and has 3D Secure enabled. Then check that the billing address matches the one on file with your bank. If it keeps failing, try using a Visa or Mastercard single-currency card instead of a UnionPay dual-currency card. When using a virtual card, ensure the balance is sufficient to cover the $20 subscription fee.
Error: Something went wrong – Network or IP Issue
This error often appears due to an unstable network environment or your IP being flagged by OpenAI’s risk controls. Switch to a native US residential IP and avoid using datacenter IPs or shared nodes. Clear your browser cache and cookies, then log in again and retry the subscription. If the error persists, try using an incognito window or switching to Chrome/Edge.
Error: Your account is not eligible – Account Risk Lock
This message means your account triggered abnormal activity detection, such as multiple payment attempts in a short period or frequent login location changes. Do not keep retrying. Wait 24–48 hours, log in from a stable IP, and submit a support ticket through the official customer service channel. Usually, after providing your account email and payment screenshots, the account will be unlocked within 2–3 business days.
