503 error after update

Summary

After update from 2.6.6 to 2.7.1 or 2.7.2 I get the site unavailable error

Step to reproduce

backup site
copy clean update
put original config file in place
run installer
installer gives no issues
continue install
site unavailable page shows
after login manager shows old version
if i try again the installer same error. Manager now gives the same error

There are around 20 similar project sites that update without any problems, but this one does strange enough

Environment

modx 2.6.6 on a subdomain
Apache

PHP Version 7.2.22

MYSQL 10.1.40-MariaDB-1~stretch

MODX version tagged when creating the issue, Apache or NGINX with version, MySQL version, browser, etc. Any relevant information.

Welcome Pierun.
What do you mean by ‘copy clean update?’
What method are you using to update? i.e. something like upgradeModx extension or something else?
