Please explain these errors, is it normal?

Hello everyone, please explain these errors to me. As I understand it, this is due either to an unstable connection of the client, or if it minimizes the browser after browsing, and then after some time it starts watching again (but these are my guesses). Perhaps the Samsung browser mobile version behaves like this, although it is on others, but less often. Also in version 6.2 this led to slowdowns and freezes, now there have been no complaints yet, but I would like to understand if this can be fixed as a way to fix it, Or give recommendations to customers, for example? Thank you
