Unity Multiplayer [Resolved] Help, unity server does not use the established port. It uses one random.

Resolved: If you mark the development build box, the bug is active. I reported this.



Edit: I deleted some things, because I reported this on Report errors. However if anyone wants to help me, here is a mor simply code, and it gives the error too.



(My english is not very good)

I have been developing an online game for a few months now, and I have even tried it and it has always worked perfectly.
The problem is that suddenly, when running the server, it takes a random port instead of 8052.

(TCP server)

Edit: Now nothing is censored. Get this code, and put it on an empty scene, with only 1 gameobject. And build it.
If something else is needed, ask me and I will publish it.


Please help. Thanks for reading.

The problem code appears to be somewhere you're not showing. The first Debug.Log statement from the code you posted which appears in your log if far after where the problem appears to occur.

Where is the code which is writing all this to the log? How is that getting written before the "Initialize engine version" line?

Hey, i think its not the code because I have an older backup of the project, and the older version worked very well at his moment, but today I started it and it starts on the same port, like the actual version. I think is windows or anything, but i dont know what is it. I disabled avast and tried another things, but the server still wrong.... Please help

 

I need solve this, where can I ask? Is there any other place where I could ask for help?

 

I reported this an error. I hope they can help me there. This error is very rare. Thanks for all.
