Sorry, but you have some strange idea about how this works. Files Gallery can be accessed in browser from wherever you installed it. You have it installed in first link, but second link isn't a folder or anything in your browser, so that won't work of course. What makes you think that Files Gallery will "create" fake links for you? This is your login page:
https://glacier.rf.gd/?login=1
If you really need a page /users/ then create it and redirect it to /?login=1 which is the applications login page. OR setup the redirect from Apache or Nginx, or even create a rewrite rule so that it looks like like it says /users/ in browser, but in reality it's ?login=1.
GLACIER I have followed each and every step as mentioned in documentation however I was not able to access the page even after multiple attempts
There is nowhere in the docs that we mention that there is a "users" page.
