Hello Community, i just installed a completley clean Server regarding to that howto: https://www.howtoforge.com/tutorial/perfect-server-ubuntu-with-nginx-and-ispconfig-3/ after i installed ispconfig i was able to see the login page in the browser. for some reasons i had to use ipv6 for that. so my login page was: https://[fd9e:21a7:a92c:2323::1]:8080/login/ when i try to login here i always get redirected to the login page again. it also seems like the session cookie is not set for that. i have that issue with chrome and firefox. didn't tried edge or safari. when i use an ipv4 adress instead. the first login after the installation seems to run flawless and i am able to see that ispconfig interface and use it. might there be a possible issue with ipv6? what did i make wrong? greetings
