Hey, just isntalled ISPConfig with: cd /tmp; wget --no-check-certificate -O installer.tgz "https://github.com/servisys/ispconfig_setup/tarball/master"; tar zxvf installer.tgz; cd *ispconfig*; bash install.sh and now after succesfull installation I just cat get on ISPConfig login screen, since it's just loading and nothing more.
Check the apache or nginx error.log file to see if you get any errors there. Besides that, the method that you used to install ISPConfig is not officially supported and might fail depending on your base system, better use the installation procedure described in the official install guides 'perfect server tutorials'.
I have this in error apache log [ 2019-02-12 12:34:40.3759 2304/7f7ed79b2700 age/Ust/UstRouterMain.cpp:422 ]: Signal received. Gracefully shutting down...

If you install that way, you may not see errors that happen during installation. So it may not be successful after all. Anyway, the apache error.log shows apache shutting down after shutdown signal. So was there any error? Is that the full error.log? Not knowing what operating system you are running, can not give better advice. But I install always using the Perfect Server Guides, so try that if current method does not work. https://www.ispconfig.org/documentation/
