AMQP 2.1.2<= fails on Bash On Windows with OperationError: [Errno 92] Protocol not available

[eugene-s]

Has error in Bash on Windows.
Windows 10 Build 1703.

Versions of packages involved:

• Python 3.6.1
• kombu 4.0.2
• amqp 2.1.2 and more
• rabbitmq server 3.6.8

I had to downgrade to version 2.1.1. It works for me.

[chungg]

probably need a new release with: #136

[darkdreamingdan]

Downgrading to 2.1.1 seems to work here too. Has #136 been integrated already? I was previously on 2.2.1 and that was causing the issue - so if #136 was merged for that there's still an issue.

[ross-urban]

I've got the same behavior, downgrading to 2.1.1 works for me as well.

So this seems to be the offending commit:

The issue related to unsupporting reuse socket port...

So, Bash On Windows and Windows don't support reuse port.

I started RabbitMQ. It bound 5672 port, after that I tried to start my python app and it didn't can be started, because in versions more than 2.1.1 using socket options reuse port.
