Intermittent error in sending messages to RabbitMQ

Question

We are getting below error when trying to send message to RabbitMQ. Our application is on .net core 3.0 on linux VM, and the RMQ server is running in a cluster of two on linux VMs. The issue is intermittent and not happening always.

Already closed: The AMQP operation was interrupted: AMQP close-reason, initiated by Library, code=541, 
text='Unexpected Exception', classId=0, methodId=0, cause=System.Net.Sockets.SocketException (110): 
Connection timed out
   at RabbitMQ.Client.Impl.InboundFrame.ReadFrom(NetworkBinaryReader reader)
   at RabbitMQ.Client.Framing.Impl.Connection.MainLoopIteration()
   at RabbitMQ.Client.Framing.Impl.Connection.MainLoop()

We have enabled automatic recovery by setting AutomaticRecoveryEnabled to true, and other than that every setting is default one.
