How to debug "The Service is temporarily unavailable"

Not applicable

I'm in the process of building my first API proxy on Edge, and I am stuck trying to debug an error message after an AssignMessage policy and right before the backend service is called. Unfortunately the trace does not tell me exactly why this fault is being raised, and I have confirmed that the service I'm trying to call is accessible and online. Attached is my latest revision.

Dear @Eduardo Garcia ,

Welcome to Apigee Community 🙂

Can you please post http request you are making to better understand issue ?

Cheers,

Anil Sagar

for me, the alternate calls are failing, i am guessing an issue with one of the message processors, which org is it? can you create a support ticket for this?

Dear @Eduardo Garcia / @mukundha@apigee.com,

For me, All the calls are failing with 503 even with basic target endpoint "http://aviationweather.gov/adds/dataserver_current/httpparam" without any policies.

This pretty much looks like an issue where Apigee is not able to connect to target backend Apigee throws a 503 back to the client when its unable to connect to the backend.

I see the same error even with Apigee API console. Simple get call fails. Check here.

Cheers,

Anil Sagar

which org you tried? maybe we are in diff env? anyways looks like the MPs are not able to reach the endpoint

@mukundha@apigee.com , I don't think it's an org issue. As i said even API Console fails to make a call. I believe target is not accessible by any Apigee Servers. Other APIs works fine from same org.

Yes Anil you are right is apigee severs not able to access the backend.

Requested support to check why the target url the fails from Apigee production setup

Hi there!

Looks like your target server www.aviationweather.gov (140.172.17.191) is not accessible from aws us-east region (We can access it from other aws regions like us-west, EU and APAC). Can you please make sure you have firewall open for us-east as well to make it work.

I don't control the firewall, this is a 3rd party service for me. How do I switch to a different availability zone?

I faced similar issue and mostly it will be due to connectivity issues. If you have solved the connectivity issue and still face the error, recommended to do all-stop and all-start
