My tag not recognized

My tags do not seem to be recognized at least by golang.
when I use go list command to check my modules, it reports error

>go list -m github.com/bon-ami/eztools@v1.0
go list -m: module github.com/bon-ami/eztools: no matching versions for query "v1.0"

while I can do the same to others’ modules, like

>go list -m github.com/sagikazarmark/modern-go-application@0.3.0
github.com/sagikazarmark/modern-go-application v0.0.0-20191115235526-e229bcc9c747

But I do not see any difference between my tag and the reference project’s. Also wonder whether it is a github issue or golang issue. Thanks a lot.

I made a new tag “1.0” without v. Now it’s same as my reference module.
For my other questions regarding golang, I’ll ask elsewhere. Thanks.
