1.

Platform reasons Sometimes the platform needs to update the system, which may cause the inability to log in. You can go to Shopee's seller group, community, backend notifications, etc. to see if other people can't log in; if no one can log in, it is a problem with the platform, just wait for the platform to recover.

2.

Network problem This may also be caused by your slow network or poor network speed. It is recommended to restart the router to see if you can log in.

3.

Wrong account and password The format of Shopee's seller account name is "XXX:main", and this must be added at the end to be the correct account, so many sellers will not pay attention to this, resulting in a prompt that the account and password are wrong; also pay attention to the ":" must be in English. If the password is wrong, you should also check whether it is a case problem, and then try it a few more times.

4.

Browser cache problem Sometimes the browser remembers the password, resulting in too many cookies cached and unable to log in. You can clear the cache and try again to see if you can log in.
