AOE 4 Error code C04T00R20X-01 50617274079B

I am unable to group of with my family/freinds or see any games in the custom games. I submitted a report to support with screenshots and everything and they did not help me at all. They gave me a bunch of information for AOE2 DE instead of anything helpful for AOE4. Information on the support website for this error does is not helpful either. I am on the same version of the game as my family which is the update that came out in August. There are no other updates to the game on steam besides that one.

The game shows an error saying that we are unable to join into a group because we have a mod version mismatch, however, we have removed all mods. Only I am unable to see custom games and join into a group with them but they can group up and see custom games just fine.

Before anyone asks if we are on the same version of the game, we checked the version what feels like 100 times (probably more like 10, but feels a lot more…) and we are indeed on the same version of the game.

Things I have done:

Ports checked and are fine.
Internet connection is fine
Mods removed
Checked Game Version
Checked Steam App ID version

And I have done other stuff with registry, etc. and other stuff that i can not remember. This has happened since the patch in August of this year.

Any help is much appreciated.

Hi, I have the same issue as you and there is no help anywhere. Did you manage to solve it?

Same issue, waiting for help too pls

Same issue any fix??

Tried to just synchronize the windows clock ?

i have too this problem and been long time

This issue still has not been resolved. Its been months and I have submitted multiple tickets. Syncing the clock does not work. Updating the ports does not work. Uninstalling and re-installing does not work. Even deleting the AOE4 folders in the documents folder does not work. This issue, at least for me, is on the Steam version of the game. I have updated the game as well, and it still has not been resolved. I’m thinking support and the devs may not see this as an actual issue.

The issue has still not been resolved. Currently updated to the newest version of the game on steam with the Knights of Rose and Cross dlc. Still unable to see any custom lobbies or get into any multiplayer games

It happened since the Knights of Rose and Cross DLC. I am suffering too.
I don’t know what the dev are doing.
Making a new bug?
