Cannot connect android phone to windows 10 hot spot PC

[braco]

I have been using Windows 10 Ad Hoc network (netsh wlan set hostednetwork mode=allow ssid=wifi key=111111111111) and
(netsh wlan start hostednetwork) for a few months with no problems at all, but suddenly it has stopped working.

I cannot longer connect to it with my android phone. I can see newly created network with internet access in networks and sharing center.

Yes, I enabled sharing on the first network in network properties. No success. Tried reinstalling system. Again, no success. Tried Baidu hot spot,

OTtoto Hot spot, Connectify with no success. My phone detects such created network but, cannot connect to it. Sometime, when trying to enable

sharing on first network I am getting a message: When Internet Connection Sharing is enabled, your LAN adapter will be set
to use IP address 192.168.137.1. Your computer may lose connectivity with
other computers on your network. If these other computers have static IP
addresses, you should set them to obtain their IP addresses automatically.
Are you sure you want to enable Internet Connection Sharing?

Any help, please.
