Why can't I pay for Subject 1 online?

Reasons why you can't pay for Subject 1 online: 1. The computer is not connected to the internet or its access area is restricted; 2. The IE version is too low, the password digits are insufficient, or the IE parameter settings are incorrect; 3. After confirming the payment on the China Unicom 10010 website and entering the PayEx secure payment platform, when selecting the bank for online payment and attempting to connect to the secure system authentication for online payment (i.e., after clicking the selected bank payment channel), it may take about 30 seconds or longer. If there is a network communication failure during this process (such as slow internet speed, modem disconnection, or being in a restricted local area network), it may cause the submission to be interrupted or fail; 4. When attempting to connect to the secure system authentication for online payment (i.e., after clicking the selected bank payment channel), if you refresh the connection page, the system may prompt: "Duplicate order error." This setting is to prevent irregular online behaviors that could lead to bank settlements.
I encountered the same issue when paying for my Subject 1 exam last time. The website kept lagging, probably because too many people were operating simultaneously during peak hours. Weak network signal is another reason; switching from mobile data to Wi-Fi made it much better. Sometimes the system is under maintenance or updates, causing pages to fail loading. Payment platform issues are also common, like insufficient bank card limits or input errors leading to failure. Browser compatibility should be considered too—some older versions don’t support it, so try switching to Chrome or the new Edge. Clearing the cache or restarting the app might help. If all else fails, wait a while or go to the DMV to pay in person, so as not to delay exam registration.
As a young person, I recently dealt with this issue and found that frequent app crashes or slow loading are mostly due to excessive traffic. Insufficient bank card balance or incorrect card number input can also cause errors, so quickly check if the bound phone number matches. Network security settings might also intercept the process, so ensure the payment environment is secure. Personal suggestion: Try a different time slot, like late at night when there are fewer users, to avoid peak hours. Check if the correct payment method like UnionPay or Alipay is selected. If it still doesn't work, update the app or contact customer service—they can check the backend logs to help resolve the issue.
