Why couldn't I log in with my account and password in the sina blog? What was going on?

If you can't log in with your account and password in the sina blog, there may be the following reasons: 1. Wrong account or password: If the account or password is entered incorrectly, the system will not allow you to log in. Please check the account and password to make sure they are correct and not leaked. 2. System Busy: If the system is very busy when you are trying to log in, you may encounter a login failure. You can try to wait for a while before trying to log in. 3. Your account is locked: If you haven't logged into the blog for a long time, your account may be locked and you won't be able to log in again. In this case, you need to contact the blog administrator to unseal the account. 4. Blog Server Failure: If the blog server fails, the login may fail. At this point, you can try using other login methods (such as email login) or contact the blog administrator to resolve this. If you still can't log in to the blog, please contact the blog administrator.
