Hi
I have installed Splunk Universal Forwarder to send messages to an indexer (version 5.0.1). The messages are being sent, but we see the following errors in our log files.

This issue is different as the client machine can connect to the server machine. I have tested that as under

wget -p http://10.90.XX.XXX:8087/services/broker/connect/E83BB6F5-448D-491D-8F9E-D497760D6087/
--08:58:03-- http://10.90.XX.XXX5:8087/services/broker/connect/E83BB6F5-448D-491D-8F9E-D497760D6087/
=> `10.90.XX.XXX:8087/services/broker/connect/E83BB6F5-448D-491D-8F9E-D497760D6087/index.html'
Connecting to 10.90.XX.XXX5:8087... connected.
HTTP request sent, awaiting response...

Also I can see the server logs with the error as posted above
ERROR TcpInputProc - Received unrecognized signature POST /services/broker/connect/E83BB6F5-448D-491D-8F9E-D497760D6087...........
