Issue with opening site

[vanyaindigo]

Hello, I have set up a website using tonutils reverse-proxy and Nginx, but I'm experiencing issues when accessing this site through different browsers. If I open it via Telegram or the internal browser in TONKeeper, the site loads with a significant delay. However, if I try to access the site through the MyTonWallet proxy, it doesn't open at all, showing the following message: "TON Site antyventi.ton is not responding."

What could be the problem?
