W10M WiFi Hotspot keeps disconnecting at lockscreen

Hello everyone,

for some reason, the Wi-Fi hotspot (I use mobile hotspot to have my laptop on the internet whereever I am) keeps disconnecting whenever my phone hits the lockscreen. So for now, the only workaround is keeping the phone active while connected - the maximum active time of the phone in the settings is 5 minutes for me. Does anyone have any idea?

Thanks in advance!
Regards,
Niko
