egroupware 20.1 docker under Ubuntu 20.04.
It worked well since (I suppose that’s this) I installed apt install php intl (for another web server).
Now when trying to accès Egroupware page I get message:
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Apache/2.4.41 (Ubuntu) Server at ubuntu-jmb Port 443
Same message if I try on http:80
What should I verify please ?
