وقتی ران میکنم اول یه پیام از طرف فایروال میاد وقتی اجازه ی دسترسی میدم این پیام در بخش کنسول میاد
Server started.
Listening for connections on port : 8080 ...
توی ویدیوی آموزشی که دیده بودم بعد از ران کردن برنامه وارد سفری شد و http sever براش باز شد، فقط ویدیو صدا نداشت من نمی دونم کجا رو اشتباه کردم و اینکه توی بخش ران کردن مشکل نداره و برنامه بازه چون اگه دوباره ران رو بزنم این پیام میاد:
Server Connection error : Address already in use: bind
فایل رو هم میفرستم
ممنون میشم راهنماییم کنید
