Description
I have multiple installations of BookStack on one server and I need to maintain them as an administrator. But If I am logged to A installation I can't connect to the B one without any troubles.
If I am logged in installation A and try to log-in to installation B then I register the problem with connecting to the installation B (error 419 Page expired). After this attempt the login session in installation A is dropped while B log-in attempt while there is no set domain - APP_URL in .env (other conditions).

Domains I have set:
first installation - example.something.something
second installation - example.something.something/Ainstallation
third installation - example.something.something/Binstallation

Steps To Reproduce
Steps to reproduce the behavior:
You should have multiple BS installations on your server accessed by path of domains with same admin name/pass combination.

Log-in to A installation as defined above
Try to log-in to B installation
The 419 Page expired error is observable (while other conditions)

Expected behavior
There should be allowed multiple logged sessions for multiple bookstacks accesses.

Your Configuration (please complete the following information):

Exact BookStack Version (Found in settings): BookStack v0.29.3
PHP Version: 7.2.24
Hosting Method (Nginx/Apache/Docker): Apache 2.4.29, MySQL 5.7.30, Ubuntu 18.04.2 LTS

Hi @suvreal,
In at least two of the instances could update your .env files for those instances with the following option:

# Instance a:
SESSION_COOKIE_NAME=bookstack_session_a

# Instance b:
SESSION_COOKIE_NAME=bookstack_session_b

Just so each have a unique SESSION_COOKIE_NAME value.
I think you're having issues as, since all your instances are on the same domain, they're currently sharing the same cookie for sessions.

Mentioned solution was successful, thank you. Whereas this fix was successful this report ticket is maybe still not closed? I guess.
