不过我理解 OP 想要让他人确定 WSL 版本之后再深究问题，毕竟听起来 OP 的的确确对这个 feature 在 WSL1/2 的改变有所认识。 中文上我们这些母语者自然觉得问题不大，但是起码英语上我认为措辞还可以稍微调整一下，来避免读者不必要的"condescending feeling"
翻译愚见： It sounds like it's on WSL1. Would you like to further look into your WSL version (to see if it's WSL 2 rather than 1)?
To my knowledge, WSL1 used to behave well, where the network traffic is automatically proxied with proxy software running in the host machine. The whole process is configuration-free, making the whole “accessing host machine’s port” just like accessing its local port in WSL.
This certain mechanism did exist on WSL1, but later became unavailable on WSL2.
To identify said problem, command output from `wsl –list --verbose` is believed to be helpful.
