Connection problem with this app.. – Telegram Messenger Review

This app is not working on my mobile it’s showing connection issue, I have been facing this issue for six months. However, all other apps are working on my mobile except this one. On the other hand, it is working on my desktop. I complained about this app many times on “ Volunteer support and Bot” but it seems useless. Please help me to solve this issue asap. Thank you
