Not compatible with LotServer (aka. 锐速) #95

Closed pexcn closed 1 year ago

I found phantun not working with LotServer, it always reports the following error:

Connection (Fake TCP connection from 10.10.110.2:1024 to xxx.xxx.xxx.xxx:xxxxx) reset by peer

But when I turned off LotServer, everything works fine.

Here attach my boot command and logs:

# server

Unsupported by Phantun as this is not real TCP protocol.
