Zero Hour mismatch error

I am having issues with synchronization on multiplayer Command and Conquer Generals Zero Hour. We have no issues starting up a match, however when we are in a match we experiance lag as well as a mismatch error.

The error that comes up is "Game has detected a mismatch. This means the multiplayer game has lost synchronization data between players"  this comes up after we have started a match and have played about 5-10 mins.

We (my friend and I) both have the Ultimate Collection from Origin.

We both use windows 10

There is no error log file (following these directions anyway) "found by typing %TEMP% into your Windows search bar. The file you need is called CNCOnline_Log.txt."

We both have the latest versions of C&C zero hour downloaded, as well as the latest version of Gentool

If you need more info, please ask

We are not using any custom maps or mods

try with activated send delay in your game options  if that help against the missmatching

This seems to have done it. Thank you!!!

I have only played one round, so it may still have problems, but as far as I am aware, that solved the issue.

allrighty glad to hear that  i will leave this topic open for some time incase there are more issues 

It happened again. Even though we both had send delay

It happened again. Even though we both had send delay

in this case we can attempt to change the way yall connect  i can send you a guide for a vpn that will do exactly that if you want and see if that helps

Sure, let's go for it

alternatively, another thing you can try is downloading an ipv4 supporting vpn like windscribe free vpn https://windscribe.com/ for which you should then create and verify your account. Once it’s installed you should have a little windscribe window on your desktop, open it and in the upper left corner you should see 3 stripes, click them, and then locate the debug menu where you should find a switch called Ipv6 which you shouldn’t touch yet as windscribe underwent an update and therefore this guide needs some work, by default Ipv6 is turned on however we want to turn it off which will require a pc restart, after the restart  windscribe should pop up automatically and to get it working with the game do the following:

1. make sure that NOTHING is draining data in the background (with a verified windscribe account you get 10GB of data monthly for free which is sufficient for just playing the game)

2. activate windscribe and wait until it’s connected, as soon as it is you can check again if anything is draining data

3. launch the game

4. in the game’s main menu go to options -> settings -> network

5. change your online and lan ip to the second available option (that starts with 10 or the one that does not match any of your ips that you might have been using with Hamachi or something)

6. connect to generals/kw/ra3 online (note that it can take a few tries until the game will let you connect)

7. start a match with your mate and see if it works

8. if it doesn’t work then try to change host and change who is using windscribe (for example you use windscribe and he doesnt but if it won’t connect then he should try using windscribe and you should disable it)

9. in some cases it can change who needs to use it over time, sometimes even both players need it

For any questions etc. ping me
