Why is the provider blocking CSS sites?

Question

css

I noticed that many sites (toster, habrahabr, yandex and others) no longer open adequately, all of them do not load CSS and not only.
At the same time, this problem in all browsers and a clean cache does not help.
For the experiment, I distributed the Internet from the phone and lo and behold, everything works in order. I realized that the problem is in the provider. Launched through TOR - they work.
What is more interesting, I launched the Windows virtual machine through parallels desktop - the sites are displayed normally.
Opened from the phone - are not displayed correctly.
I decided to raise my VPN server, I did it according to the article p.umputun.com/p/2014/08/12/svoi-sobstviennyi-vpn-z...
The result is that the IP changes, the traffic goes through the VPN, but the problem was not solved.
I went further, installed VPN TunnelBear separately, launched it through it - voila, it works.
The question is, what could be the matter and how to solve this problem? Can VPN reconfigure

Answer 1

it seems to me that you have a purely local problem in the firewall, antivirus, router or Windows

Answer 2

It’s worth writing to the provider first and if he doesn’t do anything, change it to another, more adequate one.

Answer 3

Call ISP support?

Answer 4

This is not a provider, but Adblock or a similar plugin on the browser side. Set up filters.

Answer 5

The problem seems to me to be banal provider blocks .... the same toaster is part of the res. contains on Cloudflare
For example, my toaster does not open normally without VPN. also like broken css huge icons etc.
