solid red light

I managed to get my Ring bell3 to work fully with my phone. then I followed installation steps from the app to install my chime 2nd generation, it finds the network but in the "flashing blue light" stage, when the app says "your chime is now connecting to wifi" suddenly the flashing blue light turns to solid red and gets stuck there, I tried to reset the chime , moved it closer to the router even tried moving it next to the door bell but same issue happened again and again, I'm using 2.4G. I appreciate it if you could help."
