I edited the post because I have specified the problem:
I can’t launch any projects from the editor in firefox. Chrome works fine, and yes I do have disabled any plugins and reinstalled the browser, but the problem is still there.
Everything else works fine.
Because they blocked almost all Amazon servers, which PlayCanvas uses for static data, AFIK.
They’re trying to block Telegram messenger, but they blocked almost everything except it. Lol
The whole country is laughing and making memes about that.
We can’t use PSN, Google and youtube (sometimes), instagram, local shop systems, pay systems.
We can’t even pass the captcha from Google.
I have solved the Problem.
My Firefox installation was broke in some way. I have uninstalled it wir Revo Uninstaller and reinstalled it and now it works fine.
