RabbitMQ Cluster stops working once DNS is added

Keywords: RabbitMQ - Microsoft Azure - Technical issue - Domain Name (DNS)
Description:
I setup the Bitnami RabbitMQ cluster in our Azure environment and it worked just fine. The moment I added our own DNS servers to the vNet directly, RabbitMQ stopped working... When I removed our DNS entries from the vNet's DNS settings, RabbitMQ started working again.
SO, my question is what is the proper way to setup DNS for RabbitMQ in our Azure environment? Does DNS need to be configured on the VM network interface level instead of at the vNet level or since these are Linux servers, does DNS need to be configured in resolv.conf? OR can we not use DNS?
Thanks

Hi @shaun.mcconnell,

Could you please provide more details about this issue?

What do you mean by not working?
- Did the service stop? If so, are you getting any particular error message?
- Is the service not accessible via the hostname that you configured via DNS?
Could you describe the steps that you perform for connecting to RabbitMQ, both in the case that it works and that it doesn't?
Are you trying to connect from your local computer or from somewhere else?

Please note that, by default, RabbitMQ's network connectivity is restricted to only accept local connections, for security reasons. You can find more information in this section of our documentation.

Also, we have a Support Tool that will gather relevant information for us to debug the issue. Could you please download and execute it on the machine where the stack is running by following the steps described in the guide below? You must click on the platform or cloud that you are using to find the correct instructions.

Please note that you need to paste the code outputted by the tool in your reply.
