1. Incorrect account and password: When logging in to the unified payment platform, you may not be able to log in because of an incorrect account or password. You can confirm whether the entered account number and password are correct.
2. Network connection problem: If the computer or mobile phone you use can't connect to the network or the network signal is unstable, you may not be able to log in to the unified payment platform. You can make sure the network signal is clear, and then try logging in again.
Sometimes, due to system updates or other reasons, the service of the unified payment platform may be temporarily unavailable. At this time, you can wait a while and try to log in again. The account authorizer does not access the unified payment platform, which may lead to the inability to log in or use the platform. You can consult the financial department of the school or the platform administrator to ensure that you have access rights.
