However, not all is smooth with the launch, and many players have been complaining about connection issues, with some facing the “cannot connect to server” error.

This has been one of the more annoying performance issues to deal with in the Shadow Siege event due to the fact that the error has to do with the Call of Duty servers themselves and has no permanent solution.

However, there are some temporary solutions that the community has come up with, and today’s Warzone Shadow Siege event guide will go over some of the things you can do to deal with the “cannot connect to server” error.

What causes the MW3 Warzone Shadow Siege “Cannot connect to server” error?

As mentioned, the issue stems from the Call of Duty servers themselves, and this server error will usually arise when the Shadow Siege event is facing a much higher player log-in than what it can handle.

Additionally, it can also be caused if the servers for the shooter are down themselves or facing a good deal of technical issues, preventing players from logging in.
