I tried to create my own VPN server by the guide, I have recreated all two times, but always only one problem.

Problem

• TCP connectivity test: ✅ works
• URL test: ❌ fails with "context deadline exceeded"
• Server: Ubuntu VPS
• Client: Arch Linux + Nekobox

I had created VLESS Inbound, connected to it using nekobox (btw i use arch), TCP test works perfectly, but url test crashes with this logs:
INFO[0000] router: updated default interface wlan0, index 3
INFO[0000] sing-box started (0.00s)
INFO[0000] outbound/vless[proxy]: outbound connection to cp.cloudflare.com:80
[[VLESS] Test-6ikl6wv6] test error: Get "http://cp.cloudflare.com/": context deadline exceeded
Speedtest finished.

Please help to fix this issue, tell if i need to show some other configs
