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 any proxies that may interfere with the login module. Run a security scan to remove any viruses or malware infections. Disable or temporarily uninstall any security programs, which may mistakenly identify the login module as a security threat.

Old firmware on your modem and router can cause issues with complex game connections. Visit the manufacturer's website for instructions on how to apply firmware updates.
