Hi agacrasit , Thanks for your help. Have you tried to check this problem if you connect to a different AP/ router? I suggest you update the Viber to the latest version 10.5.0.5. If this problem still persists, for exclude caused by software, please kindly try to backup phone files and factory reset. Sorry for any inconvenience.
