a 1X1 zoom meeting disconnects after about 40 minutes and asks to wait 9 minutes to reconnect.

I was teaching a private lesson via zoom and its not the first time a meeting disconnects, but it was the first time I was asked to  wait for 9 minutes to initiate a new one, which put a pause on the lesson. it then happened again afte about another 40 minutes and asked for 9 minutes again at which point my student ended the lesson.
I was led to believe that 1x1 meetings are not time limited, so why does this happen? And why am I asked to wait? I do not teach nearly enough to merit a 15$ monthly fee, especially since my native currency is worth about 1/3 of a USD. I resent being pressed to pay for a service I don't need neary often enough to make it worth the pay.
