Vps Amazon AWS vs Canvas, WebGL etc

Hello guys
Maybe someone will be can explain me this.
I made several vps on amazon. Every vps is register on different email.
I made there windows mixed OS on each , and other locations also. Every vps is different.
But when I check all servers by browserleaks.com there everywhere is same canvas fingerprints hash always same, signature of fingerprints canvas also the same on every server.
Canvas Uniqueness also on FF on every server same.
Same with WebGL - WebGL Image Hash always same on every server.
How is it possible ? And what to be do change it ?
Not work on any browser, every where is same.
Thanks in advance.

There are some Firefox Plugins that do these stuff, like canvas fingerprints blockers or even user agents switchers. Use those for a start, I recommend.

But why on every server is same ? I asked on forum before , and got confirmation that every vps is like different desktop pc example.
User agent changing not help. Canvas fingerprints blocker also can't be , because non stop will by unvisible canvas , that is suspicious for website.

I have 3 same laptop models , on every laptop is exactly same system , with same version on FF and on every 3 laptops are different canvas.
On every vps where is different system , location etc are same canvas.

Add some random Plugins. It's impossible to maintain the very same Canvas.
Also disable everything, except javascript and see if that worked.

I added some random addons to FF, but Canvas no chenged. Still show the same.
