Go version

go version go1.20.7 linux/amd64

Output of go env in your module/workspace:

GOPROXY="https://proxy.golang.org,direct"

What did you do?

when I run go list -m all to detect version of a certain lib, it hangs for more than 5 minutes:

root:/work/project# go env | grep GOPROXY
GOPROXY='https://proxy.golang.org,direct'
root:/work/project# time go list -m all
//...
real	5m39.997s
user	1m39.085s

and I found this similar issue: #60395

but I think the default GOPROXY already contains direct, also found it in the go.env here, not clear about the switching to the default GOPROXY (https://proxy.golang.org) means.

but after I removed the default direct, it indeed takes less time:

root:/work/project# go env -w GOPROXY="https://proxy.golang.org"
root:/work/project# go clean -modcache
root:/work/project# time go list -m all
//...
real	0m30.754s
user	0m9.484s
sys	0m7.601s

What did you see happen?
