Hi everyone,

We are looking into migrating most of our apps to containers, osticket being one of them.
I am in the midst of testing ,and after a long week of trial and error I am now close to finishing.
There is one last issue though that I haven't been able to solve on my own.

After pressing the install now button and the popup appears, approximately 90 seconds later it times out
with error 500.
Things I have tried:
increasing php execution time to 300
increasing iis execution time to 300
doubling VM resources
using local mysql installation instead of mysql hosted on separate container
swapping out php versions and trying different osticket versions as well.

Current setup:
osticket 1.17.3
php 8.1.18
zend engine 4.1.18
mysql: 8.0.31, on a separate windows container

my php.ini contains the following:
max_execution_time = 300
extension_dir = "ext"
log_errors = On
error_log = C:\php\php-errors.log
cgi.force_redirect = 0
cgi.fix_pathinfo = 1
fastcgi.impersonate = 1
fastcgi.logging = 0

php error logs do not contain anything after this timeout occurs
the IIS logs dont say anything helpful:

The connection to the database works, as tables are created in the database after pressing the install now button

If I missed any relevant info, please let me know

Thanks!
