Cause

Https is not enabled for Connection Docs and packets loss caused by monitoring software.

Resolving the problem

Configure IHS to enable virtualhost rewrite to HTTPS , the other virtualhost set as default .
1. Enable 80 and 443 port .
2. Config NameVirtualHost .
3. Add VirtualHost for default and for rewrite.
For example,
```
Listen 80
	Listen 443

	NameVirtualHost *:80

	<VirtualHost *:80>
		ServerName docs01.cn.ibm.com
		ServerAlias docs01.cn.ibm.com
</VirtualHost>

<VirtualHost *:80>
		ServerName docs02.cn.ibm.com
		ServerAlias docs02.cn.ibm.com
		RewriteEngine on
		RewriteCond %{SERVER_PORT} =80
		RewriteRule ˆ(.*) https://%{SERVER_NAME}%{REQUEST_URI} [R,L]
</VirtualHost>
```
The website of docs01.cn.ibm.com will not be rewrite to HTTPS . You can either use HTTPS or HTTP to open this site .
The docs02.cn.ibm.com website will be forced to use HTTPS. If you use HTTP to open this site , the request URL will rewrite to HTTPS.
Note: Monitor of Blue Coat Unified Agent could cause this problem.
If setting http forced to https, you must update concord-config.json, conversion-config.json, viewer-config.json, docs-daemon-config.json, and viewer-daemon-config.json files and change all http to https. Refer to Forcing traffic to be sent over SSL for details.
