Netflix keeps stopping what to do?

Thanks in advance, I have a problem that when I start netflix on my smartphone and look a little after 5 minutes the error code 5.7 is there. After I push it away I look further and after another 5min it is there again! I checked and all the updates for Netflix and for my cell phone are already installed.

Side information: When I look at my Ps4 netflix it doesn't happen

Smartphone: Sony Xperia X Compact

I had that too, but for me it was due to poor internet reception. Can it be because of you?

Yes it can, since the reception is not constant, so not so good internet.
