unable to connect to the cloud-hosted flask server

[iamshreeram]

Describe the bug

I am currently working with Infinity plugin that communicates with the Python Flask server. Everything functions smoothly when both the Flask server and Grafana are running locally, allowing for successful data retrieval from the Flask server.

However, when I attempt to connect to the same Flask server hosted in the cloud, I encounter a 400 Bad Request error, (With warning of 407 Authentication Error message).

Steps to reproduce

1. Deploy a server in the cloud that can respond the nodes and edges in JSON format or as a list of records.
2. Connect the Infinity plugin to the cloud-hosted server.
3. Observe the occurrence of the 400 Bad Request error.

I have also ensured that CORS is enabled on the Flask server, but unfortunately, the issue persists.

Version Details:

• Grafana version : 11.2.2
• Plugin version : 3.2.0

Additional context

I have also ensured that CORS is enabled on the Flask server, but unfortunately, the issue persists.

The request is not reaching the flask server or the VM at all. I have checked the tcpdump to verify this. So, I believe, the request is not even sent out of grafana I guess.

407 authenticationrequired meaning the infinity got http 407 from the flask server. Looks some authentication steps you are missing. Are you sure the call didn't reach flask server?

• Is grafana running in grafana cloud/srlf hosted server?
• Did you try curl the api from the grafana server to check if that is successful? What's the outcome?
• If you use docker containers, make sure to use correct/full resolvable address/container name.

[yesoreyeram]

Since the infinity calls the api from its own backend server, cors doesn't really matter. No api calls made from infinity to the api directly from browser.

@yesoreyeram , Appreciate your response. PSB answers -

1. Is grafana running in grafana cloud/srlf hosted server? - Self hosted - Enterprise Licensed Grafana
2. Did you try curl the api from the grafana server to check if that is successful? What's the outcome? - Yes, It works with curl/when we hit the api from browser without any auth. I get the json response (nodes and edges). The app as such doesn't have any auth
3. If you use docker containers, make sure to use correct/full resolvable address/container name. - Yes, We are using resolvable address

Like I mentioned, I have verified from tcpdump, the request is not reaching the application port at all when the server is hosted in the cloud.

Sorry that you having issues with the plugin. As you are already having enterprise license, I would recommend to create a support ticket. Support engineers may have access to more details who can help you quicker typically.

As an alternative.., Since this is self hosted and we don't have a reproduction steps, it is very hard to tell what's going on there. If any reproduction steps provided much appreciated.
