hi @till + others, thanks for latest update. prior updating (about 2 days before) i am no longer able to login to ispconfig with the usual url Code: https://server1.example.com:8080 After the username and password entry, i am getting redirected to the same page again. However I am able to login with .. Code: https://xx.xx.xxx.xxx:8080 I never installed anything fancy or tweaked the config. some major changes i did was 1) ahrais way of installing letsencrypt. 2) configured evasive 3) installed webftp pydio based on this tutorial. (That's not working as expected but thats a different issue. Will come to that later.) 4) i have added clients, resellers, websites to my account. Thats all. I just updated to the ispconfig latest release and the problem persists. I am feeling so scared because i already migrated all my clients website to the new ispconfig panel and still could not even figure out where to start. please help me troubleshoot. cheers.
