Hi, please test your line and check is status red or green.
if red then send line here we'll check them.
if green then ping line domain in your computer by command prompt or for mobile by using application ping server from playstore.
if domain not responding that mean your ISP block cccam server ip, the most common solution is
1- reset router (to flush blocked ips - Usefull )
2- change line server (another server ip)
3- use vpn ( to avoid blocking )
4- try by change oscam emu
