Run the test script and post the output: https://www.howtoforge.com/community/threads/please-read-before-posting.58408/ And which tutorial did you use to install ispconfig?
oh it is pound to localhost. would this be the issue? I used following tutorial: https://www.digitalocean.com/community/tutorials/how-to-install-ispconfig3-on-an-ubuntu-14-04-server
Better use a official tutorial from howtoforge: https://www.howtoforge.com/perfect-...2-php-mysql-pureftpd-bind-dovecot-ispconfig-3
can I change the ISPConfig admin page with https://mydomain.tld:8080 to https://portal.mydomain.co.uk?
