Pro - libreoffice collabora

I’ve upgrade from pro 5 to pro 6 on Ubuntu 16.04 and cannot get the libreoffice preview working for the life of me. I did the docker commands and suspect my problem may be here:

sudo docker run -t -p 9980:9980 -e “domain=” --cap-add MKNOD collabora/code

I keep getting an error:

Getting CA Private Key

wsd-00023-00 00:00:00.000763 [ loolwsd ] Log level is [8].
SAXParseException: Tag mismatch in ‘/etc/loolwsd/loolwsd.xml’, line 39 column 109

I followed the collabora link in the manual page and ran this command:

sudo docker run -t -d -p -e
“domain=” --cap-add MKNOD collabora/code

which returns a string of charachters and no errors. At any rate after adding the code to I can’t access my server at all. Of course I can redo and access fine.

Bottom line I can’t figure it out and need some hand holding here. I have libreoffice installed from the links in the manual and even tried the older versions.
