There is an option to tell Vim where to look for tag file.

I use the following configuration:

" search first in current directory then file directory for tag file
set tags=tags,./tags

Extract from help :

When a tag file name starts with "./", the '.' is replaced with the path of the current file. This makes it possible to use a tags file in the directory where the current file is (no matter what the current directory is). The idea of using "./" is that you can define which tag file is searched first: In the current directory ("tags,./tags") or in the directory of the current file ("./tags,tags").

For example: :set tags=./tags,tags,/home/user/commontags

And I keep my current working directory in the top project directory where my tagsfile is generated.

Use :pwd and then :cd myproj (inside Vim) to go to the directory containing your tags file.

See :help tags-option for more information on tags path.

You issue is probably that you are either in the wrong directory, or your tags option is not properly set.
