I cant install the WebAccess 18 on a SLES12/3 server.

now I use a fresh SLES12/3 installation and install only the webaccess option. (language english. There are lots of problems if you try to install GW18 with language german!!!!)

after the installation we enable SSL for apache (I use this tutorial from Micro Focus https://www.youtube.com/watch?v=wgWx-EQOkK4)
after this we fix the auto-start problem for tomcat at SLES 12 TID:https://www.novell.com/support/kb/doc.php?id=7022475

but we get the error "SSL-ERROR_RX_RECORD_TOO_LONG"

with netstat -peanut | grep 443 - tcp :::443 listen

any ideas?
