connection to ftp server kost when phone lock screen comes up

[AlexBierig]

Hello

I'm new to the forum, aged am I some 70 years

I think,the power ftp is just what I was looking for. I will buy it.
But it loses the connection phone -> ftp server ( ftp server used as client) when the lock screen of the phone comes up.

Android smart phone, Android 13, latest version of PowerFTP; FTP Server: IIS 7.5 running on Server 2008R2
It is all in the lokal intranet, which is working behind an OPNSense firewall.
Connections only are established inside the lokal intranet, which works for me fully satisfying.

The question now is: will there be an update, that keeps either the connection, even a phone lock screen appears or which stops the phone lock screen coming up, while a transfer is running?

Hope it is clear, what I mean

greetings
Alex
