Thank you for your response! I completely understand now.
Hi, today I tested the Join process using the JoinByToken method.
There were no issues with hosting, but when trying to join, even though I entered the correct Token, I got a Web Server Error 604.
Additionally, GetServerList did not return any results.
So, I checked the logs and found the following messages right after successfully hosting:
UnrealHostPlugin: TCP Server started on port: 8000
UnrealHostPlugin: TCP Server stopped: 8000
UnrealHostPlugin: Remove Host: 3EJ8hM
Could this be the cause of the issue?
You must activate “Is Public Server” in the “Start Host” function so that it appears in the server list. The “Host Token” also comes from the “Start Host” function.
I’ve already done that…
Or, could it be because hosting takes an unusually long time to connect, although I’m not sure of the exact reason?
Have you entered the correct ipv6 and ipv4 in the web.xml? This could be the reason why it takes so long. The client tries different things to connect.
Otherwise you can also activate the logs in the web.xml. Then much more is written into it.
Oops, I had entered a value other than my IPv4.
Thanks to you, hosting is now much faster!
However, there still seems to be an issue with the Join process…
Hard to say from here. Perhaps deactivate the firewall to test whether this is the cause. Does the demo build in which my server is registered work? Does the demo project work with your server?
+++ Web Server Error 605 appears, followed by another 604, and then the process fails. And Your demo project worked perfectly
This could be because you have entered 0 for server slots. This is the maximum number of players that can join.
Hmm, this time I tried changing the ServerSlots value to 2, but it seems to be the same as before…
Just to be clear. Did you take my demo project and enter your server data there and it worked?
No, I used your demo data exactly as it was.
I’m not sure of the exact reason, but after placing SetAllowClientsToJoin right after the StartUEGameHost method, it worked successfully!! But manually entering the token and triggering JoinUEGameHostByToken still doesn’t work.
You can enter your server in the demo project and test it to see if there is a problem with your client or your server.
You could also try to create a build and start it twice. One for the host and one for the client.
In my project, I still get Web Service Error 605, and while hosting works, joining doesn’t. Even after refreshing, the issue remains the same.
I looked in the code. 605 is returned if joining is not allowed. Joining is only allowed when the host is fully started.
Stop the tomcat. Delete all log files. Activate the logs in the web.xml file. Start the tomcat. Start the host. Copy the logs (catalina) here.
Is the log you’re looking for catalina.2025-03-17?
Yes, I don’t know if it wouldn’t be better to switch to e-mail.

I don’t see anything from my app. Is this after you have started a host?
