Problems

WebApp doesn't work in web.telegram.org

💁‍♂️ If you use WebApp through the web.telegram.org, then Nginx will be very reluctant to give statics (WILL NOT).

🧐 This is caused by the iframe security policy, which needs to be slightly adjusted in the Nginx settings.

✅ I am attaching a solution to the problem in the screenshot. If you have security settings defined in Nginx, then look for such a setting in your configs and edit it as in my screenshot.

⚠️ Don't forget to use nginx -s reload to update your config changes!

😎 As a result, Nginx will be happy to share static files with users of the web.telegram.org

White Screen in TDesktop

💁‍♂️ TDesktop on a PC does not know how to use TLS 1.3, so be sure to specify the ability to use TLS 1.2 in the Nginx config.

P.S. 😕 Now it seems too early for TLS 1.3
