AMQP traffic LB through standard VS. Error = PROXY protocol header signature is not recognized.

Hi. We're trying to LB a cluster with three rabbitMQ (AMQP) servers.

The traffic on a Standard VS should LB to the pool members, the aforementioned rabbitMQ (AMQP) servers. We put the irule for proxy protocol (https://devcentral.f5.com/codeshare/proxy-protocol-initiator).

when CLIENT_ACCEPTED {

 set proxyheader "PROXY TCP[IP::version] [IP::remote_addr] [IP::local_addr] [TCP::remote_port] [TCP::local_port]\r\n"

 }

 when SERVER_CONNECTED {

 TCP::respond $proxyheader

 }

But at the end we received below error message:

"The PROXY protocol header signature was not recognized. (PP 2.1, PP 2.2) "

PROXY protocol has already been enabled on rabbitMQ.conf.

Seems if the PROXY protocol version is not accepted.

Anyone can help with this issue? Thanks in advance.
