NimbostratusHTTP monitor issue
I have a VE machine, BigIP BIG-IP 11.2.1 Build 807.0 Hotfix HF1
When trying to create a custom HTTP Monitor with custom headers (as seen in https://support.f5.com/kb/en-us/solutions/public/2000/100/sol2167.html)
the monitor then returns Error 400 Bad Request, when tracing we see that the headers arrive twice in the same request.

Can you post your monitor configuration please (minus sensitive data)?

It may be worthwhile to troubleshoot this from cURL on the command line. Use the -v option for extra verbosity, and use the -H option to add additional headers. Example:
curl -v http://10.10.10.10/api/charm/monitor -H "Host: myhost.com" -H "User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:23.0) Gecko/20100101 Firefox/23.0" -H "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8" -H "Accept-Language: en-US,en;q=0.5" -H "Accept-Encoding: gzip, deflate" -H "Connection: keep-alive"
