Your ROOT_URL in app.ini is https://git.bwnetwork.us/ but you are visiting http://git.bwnetwork.us/Administrator/Splunk_Docker/src/commit/d59c1fc90e884995e54f8d3731547e612a54c162/files/splunk-etc/system/static/moreAppsIcon.png
You should set ROOT_URL correctly, otherwise the web may not work correctly.
