Pls help on below issue:
After installed the mysql5.6/commutity server(latest)/control panel(latest)/document_server(latest) docker versions, after I set the document service address and click save, it reports “Docbuilder url: download” message. It will pop up a “download failed” error window each time when I try to edit a document.
Those containers are installed on a centos7 server with kernal version as 3.160.0-1062, no internet access.
Browser is Chrome90.0.4430.93.
