I test in anther vps with otp 23.3 , this bug was fixed. "{inet_backend, socket}" option could listen mutiple sockets

Should be fixed in the next OTP-24 release now that erlang/otp#5122 is merged. I will close the ticket. Thanks for the reports!

I read erlang/otp#5122, and Raimo tagged it for milestone 24.1. So I guess the fix won't be available before that, right?

[essen]

Sounds like it.
