Still no luck can you please suggest anything which would work

Answer 1

You can tag it later and run git push --tags to update the tags to the remote repo, so you never miss it. But in some teams, to push tags may need permission.

Answer 2

Now, suppose you forgot to tag the project at v1.2, which was at the commit. You can add it after the fact. To tag that commit, you specify the commit checksum (or part of it) at the end of the line for this case its 6fcub07:

$ git tag -a v1.2 6fcub07

You can see that you’ve tagged the commit:
