hi, can you please help me with xtls vision?

[Amin2460]

Hi. I'm an Iranian. Have a USA vps. The ip is unfiltered and ports are accessable from Iran. But tls configs (ws tls, tcp tls, trojan ,etc) are having a lot of problems! It connects but the ping is very high, like 2000 when it should be 800 at most, and it's very unstable, it disconnects randomly and gives "tls handshake timeout" and has awful speed and ping. It only happens when I'm using tls. This is probably sth to do with government blocking. I have heard that xtls vision can solve this "tls handshake timeout" error. I installed x-ui. X-ui only has tls with vision flow, not xtls with vision flow. Is it okay or does it have to be xtls?? + I saw you mentioned something about fall back to fake ngingx website. How exactly can I do it? For example, I wanna make a vless xtls vision config with fall back to ngnix website. So steps are like this ?

1: setting up an ngninx server on port 443 or 8443.
2: making the config and putting the nginx hostname in the SNI field?

Please help a bother out. I'm confused , and frustrated. I'm also willing to give you the vps credentials to set up whatever you want, because I only know how to use x-ui.
