Log in / registration 404 - error

[0develoqer]

I have issues with log in or registering a new account on client ver. 6.1.1c, I get 404 error. What i am doing wrong? (Using Windows 10 with hotspot connection & Android 11 (32bit) tablet to run Arcaea app)

I was using using proxy charles and proxifier on my android device (I also use hotspot connection and I haven't seen this issue before on 5.6.0c). I got some help to set it up. Yet i cracked ssl pinning on my client using IDA and I still have issues. I'm not really sure what I was doing wrong.
This is what my cmd terminal prompts when I try log in(registering shows the same and doesn't let me) and opening the client.

And the client:

(And honestly, i don't know,
wich one I was supposed choose to open this issue in Q&A or bug report)

Check your setting option GAME_API_PREFIX in config.py. I guess it is not "/coldwind/35".

If you didn't change this option, please check your server version.

Game api prefix is /join/21 and the server verision is 2.12.0
