Unable to process parse X-Forwarded-For correctly

[MEM-917]

After updating to the newest cores and checking logs for haproxy, nginx and xray, although IP entries passed over to xray register for Reality and gRPC, WebSocket doesn't register client IP. For more investigation, I downgraded the core to 1.8.16 and everything works flawlessly.
Has anyone else noticed this?

Might be a bug.
What is "register client ip"
please follow the issue template

What is "register client ip"

Client's real IP. Whether it is behind the CDN or it is the real IP.

In these tests, only the core has been changed and all the configs of nginx and haproxy are the same.

Here is the log of 1.8.18:

[Fangliding]

what are you using to pass source ip, proxy protocol? or X-Forwarded-For?

[MEM-917]

I use X-Forward-For because by using"proxy_protocol", the real IP of the client behind CF cdn can't be obtained with gRPC protocol.

[Fangliding]

It seems that a small change in WS has break it, we will fix it

Thanks, I'll try it now and will let you know.

EDIT: It works like a charm. Thanks, man.
