Failed to start WebSocket server: Port <PORT NUMBER> is already in use

[firdiar]

Following this closed issue : #28

actually issue still happening on my end sometimes maybe at 50:50 chance

[MCP Unity] Failed to start WebSocket server: Port 8030 is already in use. Only one usage of each socket address (protocol/network address/port) is normally permitted.

The work around i do is usually changing the Port to another number or restarting unity

im checking the task process running at that port when it failed to start and this is the result

after i restart unity the task is disapear, and i can start normally. and this is how it's lookslike on fresh start

i think, somehow the process got stuck while recompile happens forcing the MCP server to restart but the old server is failed to stop completely.

should we have an option to ForceRestart the server?

PS: Let me know if you need any assistance to test it

appearently it's happening even without so many task listed on port

this time the server runs without me running the AI agent, so no connected agent then recompile the script

Hello @firdiar

Thank you for the report. I pushed a fix with a delay to confirm the websocket is properly setup.
I also hadded a Restart button to help in case of race conditions error.

Let me know if help

Just let you know that I'm aware of the update and still testing it.
So far so good for me. I'll let you know again after several days of using it.

Ok, this is very strange.
Can you give me the step by step execution you do @firdiar ?

I am wondering now if this is a PC Windows problem

这个bug在unity6中发生的概览比较小，但是在中国版unity（团结引擎）项目中，这是个高频复现的bug。我通常是重启unity来解决这个bug。
