Help me! Traffic does not pass through VPN (3X-UI panel)

[Mirosha888]

Hi!

I installed 3X-UI on a VPS with OpenVZ. And didn't even manage to get into the panel :)

But here is not the problem. The clients I created, when connecting to VPN (which goes fine), don't get any traffic at all. The Internet just stops working after connecting to VPN on all protocols that I tried VLESS, ShadowSocks.

Please tell me where to dig. Thanks, friends!
