if the issue is possibly on the client-side, then mention some of the following:

• the device type and model: Samsung Galaxy A55 5G
• OS version: Android 16
• browser version: Chrome 141

Additional context

Client doesnt connect at all. It doesnt connect using http and ftp. The FTP client i used is Samsung My Files using the network storage feature

you are trying to connect to the http/https port with ftp; you will need to enable the ftp-server (disabled by default) and connect to the port you choose for that. See the example config in the readme: https://github.com/9001/copyparty#ftp-server

beware that, if you have a firewall, you need to open tcp ports 3921 and 12000-12099 according to the values you choose
