Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Different network version number for same code builds

Hi all.

I am trying to build dedicated server for linux on my linux computer. And at the same time I am trying to build client for windows on my windows computer. Both Development build. After all I can't connect from client to my Linux DS, because

[2016.06.22-18.34.42:684][ 0]LogLoad: Took 0.080499 seconds to LoadMap(/Game/Maps/MAPNAME) [9:39] NotifyControlMessage: Client connecting with invalid version. LocalNetworkVersion: 334850937, RemoteNetworkVersion: 2077486219

(server log)

I am building same version of code on same version of Unreal, but on different PCs, and getting different version number of builds.

The Question is how can get same version of network and same version of build on same code but on differents PCs to compile?

Hey lab-one-

There are a few questions I'd like to ask for additional information and to help me understand and reproduce the problem:

  • Are you using source builds for both Windows and Linux version of the editor?

  • If so, were they both downloaded from the same branch at roughly the same time (both from the 4.12 branch one after the other, etc.)?

  • If you are using the binary version (from the Launcher) for Windows and a source build for Linux, or are using two source builds where the source code was obtained at separate times, it's possible that there were changes that went into the branch between when you downloaded the second source version that would cause them to have difference engine versions.

  • Can you try creating a new project on each OS and let me know if you still have problems connecting them?

  • Also include the setup steps to help me reproduce this issue locally.

Hello Doug Wilson, thank you for your answer.

You're right, on Windows I am using your binary version, and for Linux I am using last source build.

First of all I will make my builds with same version of your nice engine.

And if this wont help, I will reproduce this issue at nearest weekend with step by step description.

Hey lab-one-

Were you able to build the server/client with the same engine versions on both platforms? For tracking purposes I will be marking this as resolved for the time being, if you are still having problems with the server/client feel free to comment and we will continue investigating.

Hi. Sorry. I was unable to do build my game for this days. I will write here about my results in the couple of days.

Hello, we also have the same problem. LogNet: NotifyControlMessage: Client connecting with invalid version. LocalNetworkVersion: -315694076, RemoteNetworkVersion: 69432638

We use the same project only on Win10 or Win7.

Okay, we had one client with an UE 4.13.0 and two clients 4.13.2. Just take check this first if you encounter the same problem.

I couldn't find where to change the tag. Could you please explain how can I do this?

I think you have to create or migrate the project into the same release of Unreal Engine. Otherwise it will have a different release tag.
