WebSocket Connection Rejected (200 OK) When Connecting to RDP Server

[alvianaufan]

Hi, I need some help. I’m encountering the following error:

2026-01-14 01:59:14,592 - rdp-server - INFO - Starting RDP WebSocket server on ws://0.0.0.0:8765

2026-01-14 02:03:37,347 - websockets.server - INFO - connection rejected (200 OK)

When I enter the target host, username, and password and then click Connect, I encounter these errors.

How can I fix this issue?

ws://localhost:8765, it will cause problems if it's not accessed locally.

Temporary solution:

root@livecd:/home/acha/rdp# docker exec -it rdp-frontend sh
/ # cd /usr/share/nginx/html/
/usr/share/nginx/html # sed -i 's/localhost:8765/178.120.2.212:8765/g' index.html 
/usr/share/nginx/html # 
root@livecd:/home/acha/rdp# docker compose restart

显示效果，期待优化。
