Errors with http/https

Hello.Hello.

I use xwiki docker image 10.8 from https://hub.docker.ru/_/xwiki/ and nginx image as reverse proxy (and https-server).

Main wiki is located in ROOT folder (https://wiki.xxx.ru)

If we leave unchanged xwiki.home parametr in xwiki.cfg - we get some errors:

1. some strange resource link errors in web console

• i.e. jquery.js:5799 GET https://cedar.xxx.ru/resources/icons/xwiki/spinner.gif 404 (Not Found) in this case I just don't know where from is cedar.xxx.ru subdomain (we have this address in organization, but why wiki is trying to get spinner.gif from there?)

1. Some resources cannot be loaded, links are build with port 80 for them (for example in notification panel - avatar images), i.e.:

• GET https://wiki.xxx.ru:80/bin/download/XWiki/iaginder/keha.jpeg?width=40&height=40&keepAspectRatio=true 0 ()   
• GET https://wiki.xxx.ru:80/bin/skin/resources/icons/xwiki/noavatar.png 0 () If I set xwiki.home parametr in xwiki.cfg - we have no that errors, but get another ones:

If I set xwiki.home parametr in xwiki.cfg (to https://wiki.xxx.ru) - we have no that errors, but get another ones:

1. In Main wiki (https://wiki.xxx.ru) errors with rest links i.e. in notification panel - when open it - get such errors

• GET https://rest/notifications?media=json&userId=xwiki%3AXWiki.abtarano&useUserPreferences=true&count=10&displayReadStatus=true&_=1539654980203 0 ()

or error when trying to delete some page:

• GET https://rest/jobstatus/refactoring/delete/1539654907694-325?media=json 0 () ...

Deletion process freezes on "Please wait while the page is being deleted.". This error is displayed in web console, but the page is deleted.

BUT this functionality works without errors on subwikis (i.e. https://wiki.xxx.ru/wiki/test/) (with xwiki.home set to https://wiki.xxxx.com)  - notification panel is displayed (and avatar images are shown) and pages are deleted without errors (rest links : https://wiki.xxx.ru/rest/...)

There is also problem with page creation from page template (whatever xwiki.home property is set) - similar to https://forum.xwiki.org/t/page-hangs-on-save-save-0-however-save-is-successful/352
