NPrinting Rabbitmq server is not connection

mstoler — Tue, 20 Oct 2020 20:20:24 GMT

Hello,

I am having problems with my NPrinting system. Specifically I cannot open a report or a connection.

When I look at the log files for the web.engine the message below appears:

RabbitMq server is not connected - trying diagnoser queue creation again in 10 seconds many times

I have followed the article support.qlik.com/articles/000044459 to reinstall rabbitmq. It looks like rabbitmq is successfully running.

What else can I try?

Thank You,

Michael

It's possible that your NPrinting Server has been manually set to listen in plain text. Were any settings changed on your NP server to enable plain text?

Using an admin command prompt, run the following (use the correct sbin path in your environment) to diagnose.

C:\Program Files\NPrintingServer\rabbitmq_server-3.7.24\sbin>rabbitmq-diagnostics.bat status

You should see this in the 'listeners' section of the status output command:

If you see extra lines including http, then it may be listening in plain text.

In this case you would need to reverse any changes made to enable plain/clear text listening.

The other possibility is that you need to

Uninstall the NPrinting engine
Re-install the NPrinting engine (ensure the engine is the same version as the NP server)
In the NP web console, delete your NPrinting Engine entity, recreate it, then resend the certificates to solve the issue.

Hello,

Yes I did a complete reinstall.

So far so good.

Same but I had to re-init RabbitMQ following https://help.qlik.com/en-US/nprinting/May2022/Content/NPrinting/Troubleshooting/Qlik-NPrinting-Messaging-Service-startup-connection-problems.htm#Fix_the_messaging_service_users_and_permissions guide .
