Redmine

I am seeing issues with redirects after login. When I go to an issue URL while logged out I expect to be redirected to the issue after logging in. I'm seeing this on.

Steps to reproduce:
log out
go to /issues/12345
I get redirected to /https://XXX/login?back_url=https%3A%2F%2FXXX%2F
log in
I get redirected to /my/page
expecting to be /issues/12345
