Transmission error is a nuisance that has existed in the previous Call of Duty titles starting from Modern Warfare. Since both Vanguard and MW shares the same game engine, a lot of error that occurred in the MW has returned in Vanguard. Some players are reporting that the error that prevented them from playing MW is back in Vanguard and they cannot continue with the game. Fortunately, the Vanguard Disconnected Due To Transmission Error does not prevent you from launching the game, but disconnects you mid-way, which suggests it could be a problem with your connection or an issue with the servers. Here is what you need to do to fix the error.

CoD Vanguard Disconnected Due To Transmission Error Fix

The Vanguard Disconnected Due To Transmission Error is self-explanatory. It occurs when the transmission of data is hindered between the client and the server. If the game fails to communicate with the server due to any reason, the error can occur.

At the time of writing, this seems to occur mostly when you attempt to join a game hosted by another. If that’s the case with a large number of players, it could be a bug with the game. Please let us know in the comments if you face the error in a similar circumstance.


While the server may not be down in most cases when you get the transmission error, it’s worth checking the status of the server. Visit a third-party website like Downdetector that has user comments or you can go to Reddit. As this error does not occur when there is an outage, you may not find help on the game’s Twitter.

If the servers are fine, some of the things that can help fix the Vanguard Disconnected Due To Transmission Error are:

  1. Ensure that the NAT type is set to Open
  2. Verify or Update the game files
  3. Try factory resetting the router/modem
  4. Try changing your ISP or try playing the game using the Mobile hotspot.

These are the best solutions to fix the CoD Vanguard Disconnected Due To Transmission Error. We will update the post if the issue escalates or there is news from the devs.
