Problem connection (ban ip ?)

Good morning !
I am creating this ticket because I assume I have a problem with your service.
It started now 1 month ago!
Let me explain, I try to go to sites for dl software, these sites are hosted on clouadflare and I can’t connect. I have error 1016. And it doesn’t only happen on sites but also when I try to dl apps (install) (not the same error)
I don’t know if the problem is yours or mine. I have no restrictions, I have of course tried to deactivate my anti virus, restart my pc but nothing works!
If you know how to solve the problem, you will be a great help!
Thank you in advance and good day !
