Domain fronting and change Sni

[mahdimirzayi120]

Hi everyone
I have v2ray websocket server and I used a CDN and domain fronting to prevent IP blocking. Actually i use a valid domain in SNI field and the origin domain is in the camouflage host which encrypts in tls (the SNI is example1.com).

Now I have to use another server as a relay to connect to the cdn and main server. It works well by tcp forwarding to a custom CDN ip address (gost -L=tcp://:443/X.X.X.X:443)
But I want to use a second cdn to connect to the relay server. So i have to change the first valid SNI in V2rayN panel to a registered domain in second CDN! (this SNI is example2.com)

Can you please help me how can I configure the relayed server and change SNI (Server Name Indication) example1.com to example2.com ??

I need it urgently
Thanks in advice 🌹
