Proxy Log: Bad request, malformed first

[jmmolero]

Hi,

I find an issue in "Log\Proxy\Trace\QLIKSENSEPXP02_Audit_Proxy.log", this log shows a lot of times  this warning message:

"..Audit.Proxy.Qlik.Sense.Communication.Communication.Header.HeaderParser .... Bad request, malformed first line: GET /↵↓ [xxxxx-....]"

This issue happens at consumer nodes. Central node appears be fine.

Consumer nodes are working but something's not right and I want to fix it. Does anyone know the cause of this problem?

Attached is a sample of the log.

Thank you.

Given that the frequently is pretty much every 5 seconds, this smells like a health check from some device (e.g. load balancer, etc).
