[lesquoyb]

Describe the bug In the current version, gama-server do not start anymore. When running it, the initialisation goes normally:

but then nothing happen while we should see a line explaining that the server is running on a certain port. Of course no client is able to connect to it. This only happens in pure server mode and the server seems to run normally in gama gui

To Reproduce Steps to reproduce the behavior:

1. Run gama-server either from eclipse or with the gama-headless script
2. see that initialisation never reaches the Server started point

Expected behavior It works as it used to do

[hqnghi88]

The "Server started" message is not written anymore in onStart() of headless server (it is in GUI server). But i can connect to server by JS , can you report more detail on your failing case that no client could connect to server??

[lesquoyb]

well that's weird because that text is showing when you run the gui version. Anyways I just run my usual test python script that you can find here and it gets stuck at connection with server, but it works as expected with gama gui

[RoiArthurB]

Same as Baptiste, we tried to connect it and, what I noticed, the port and the web socket seemed to somewhat start, but it's impossible to actually connect to the server (Timeout error) :/

[hqnghi88]

No problem on my side even with your py code.

[RoiArthurB]

@hqnghi88 via GAMA headless from Eclipse or build alpha ?

[hqnghi88]

Headless product in eclipse

[hqnghi88]

even with binary release

update on my side: I tried with another computer and couldn't reproduce the issue. The server started text is not displayed but looking at the code it's fairly normal as it only is printed in gui server now, but apart from that I'm able to interact normally with it. That other computer is a windows 11 one, just like the one I used in the first place

[RoiArthurB]

Works on Linux too, I think it would be better to have the server message also display in the headless' logs :thinking:
