Unable to access the web side after startup

[cicitutu]

I deploy the service on the server. yarn dev starts the front end program. The screenshot message as above appears. Is this correct?
Then I can't access with my ip:5173

Here's my back-end service startup

I would like to know how to solve this problem of not connecting to ws

I used nginx as a proxy between the web side and the server side.
