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"

Error: ReceivedRPC

Recently I`ve updated my project from 4.15 to 4.18 and now some times the client losing the replication with dedicated server and rising the errors in log:

I have also encountered this problem when upgrading to 4.18. I have been working on this for a couple of weeks without finding any solution.

I have this problem too

I have begun to come to the conclusion that this issue is a result of changes made in 4.18. I'm rebuilding a 4.17.2 version of the engine to make sure. @Epic needs to address this.

Hey everyone,

I'm currently looking into this, but it would be a great help if I could get a project that showcases the issue so I can do some debugging.

Please refer to the following thread for information on how to private message me a link to the project: https://answers.unrealengine.com/questions/730523/replication-errors-in-418-close-client-connection.html

Also, please keep all correspondence related to this issue. in the linked thread. Let's move the discussion over to there.

Thanks

I know this was a while a go but, I've been scouring the net for answers regarding a semi similar issue we are having in 4.18. Basically when we connect two players together in a direct ip connected lan game and the client calls a server rpc that changes a replicated variable, it disconnects the client and kicks him back to the lobby level. The variable it changes is a boolean that is simply used to set the visibility of a laser pointer component we use. This post is the closest I've been to finding any information remotely similar to our issue.
