Management UI shows queues but I cannot access them (Not found error)

[Santiago Acosta]

Hello,

Up until a few days ago I migrated my experimental RabbitMQ Server single node from 3.9.x to 3.10.5. After the upgrade, the Management UI stopped accessing the queues. I can navigate anywhere I want but I cannot access the queues by clicking from the queue manager.

The error on screen is

> Not found

> The object you clicked on was not found; it may have been deleted on the server.

In the Network tab, the response is a 404 with a body

{"error":"Object Not Found","reason":"Not Found"}

The same applies when trying to access a queue from an Exchange manager's Bindings entry. It also applies to streams and to queues from other vhosts.

I am not using the default vhost (/), I am working with one with a normal name (blue), but the default one does exist.

My user has full access and is also tagged as administrator.

There is nothing in my logs (any of them), only normal operations, no errors, no warnings.

The UI does show the queues being updated as more work comes in so everything underneath is working as expected. The issue seems to be only at the Management UI level.

Am I missing something? Did I screw up the migration?

Hi,

Can you share the logs, especially access logs for the Management UI/API?

Also, I assume it's purely a Management problem, right? You can publish/consume messages, can see the queues in `rabbitmqctl list_queues`, etc?

Thanks,

Sorry guys. I restarted the server a couple of times and now everything is back to normal again. Yes, this was purely a Management problem. Everything else worked just fine.

> Can you share the logs, especially access logs for the Management UI/API?

I do not have specific logs for the Management UI. The only log I have that has any relevant information is the default log at "/var/log/rabbitmq/rabbit@<hostname>.log" which does have access attempts. But I've scoured these logs from top to bottom and there is not a single sign of Management UI problems or any other problems (apart from some service clients reconnecting here and there).

If I can generate unique logs for the Management Plugin, that would be fantastic. Is there a configuration option for that? I'll go dive into the docs

Hi,

Glad to hear it works. The management plugin has logging configuration:

Best,
