Common Problems
Failed to download a required update. Please check your internet connection and try again. BLZBNTBTS0000004A
This error is usually caused by an unstable internet connection or a third-party program that is blocking access. Follow the steps below to resolve the issue.
If you're using a wireless connection, optimize your internet connection to rule out a connection issue.
Try closing background applications to resolve any software conflicts.
Disable or temporarily uninstall any security programs, which may mistakenly identify the login module as a security threat.
Delete the Battle.net Tools folder to automatically rebuild outdated or corrupt files.
Run a security scan to remove any viruses or malware infections.
