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"

Local Dedicated Server Guide Issue on 4.21

I followed the guide linked here, https://wiki.unrealengine.com/Dedicated_Server_Guide_(Windows_%26_Linux), and came across an issue of not being able to connect to my local port. The server executable runs but I believe the logs are incorrect. Instead of saying listening on port 7777, it says this towards the end,

If these logs are correct, then I'm still unable to connect when running the client program as the join messages do not show up on the logs either.

I also ran netstat -aon | findstr :7777 in command prompt to see if the server was actually running on port 7777 and it wasn't.

Update: I had some code in my gamemode.cpp file for implementing amazon gamelift when I was trying to just test localhost. Therefore, the logs above were correct but it was stuck waiting on an amazon gamelift program to run before running on port 7777. So I removed this code and rebuilt but now I'm getting this error,

It's been a while since I've asked this question, but I eventually added some files to the folder where my server executable was located to help me debug my issue further. Basically, I took all the server files (not just the executable) from my Binaries/Win64 folder

alt text

and copy and pasted them to the same folder where I copy and pasted my server executable to when I built the project. In my case it was the WindowsNoEditor/{NameOfProject}/Binaries/Win64 folder.

Now when I run the server and it crashes, I get a more descriptive reason in the logs as to what caused it to crash. In my case, it was that I did not check whether or not GetController() was nullptr before using it in BeginPlay in my Character class. I added a HasAuthority check to deal with it, since GetController() will return nullptr in BeginPlay on the server only.
