1. Confirm whether the account number and password are correct: Please confirm whether the account number and password you entered are correct, and make sure that the case and special characters are consistent. If you forget your password, you can try to find it back or contact the relevant department to reset it.
2. Confirm whether the network connection is normal: Please ensure that your device is connected to a stable network connection. You can try refreshing the page or trying to log in with another device.
3. Check the system maintenance: If there is a login problem during the system maintenance, it may lead to abnormal login. In this case, please wait until the system maintenance is completed before trying to log in.
If you have checked according to the above steps, you still can't log in to Lanzhou Maintenance Fund. I suggest you contact the customer service department of the fund to describe your problem in detail, and they will give you more professional help and answers.
