Zoom is not working fine

I am using zoom for 2 years and it was working fine. But for the last few days, it is not working properly. I am a guitarist and teach guitar to my students by using zoom. I was delivering a lecture about the top Best acoustic electric guitar cutaway and a sudden zoom meeting was cancelled. I am trying to reconnect it but it is not connecting. I also check the internet connection and my laptop everything is working fine but there is a problem with zoom. Please do let me know that how can I sort out this issue?
