I am trying to connect to a remote rabbitmq server. I have the correct credentials and vhost exists on the remove server, but I cannot connect.
I get the error 

pika.exceptions.ProbableAccessDeniedError: (530, 'NOT_ALLOWED - vhost
  test_vhost not found')

I have struggled with this for a while but I can't seem to get what the problem is.
I figured it out. On my local machine I am using rabbitmq version 3.5.7 while on the remote rabbitmq is on version 3.7.0
I had been declaring my vhost without a slash '/' on 3.5.2 and it has been working well but I realized that adding a slash before declaring the vhost worked on version 3.7.0 .
So now I use /test_vhost instead of just test_vhost
RabbitMQ Error 530 vhost not found with pika
