Hi @keijack I am having issues with connecting my python fastapi app to the discovery server on a UAT environment. However, I have no issues connecting to my discovery server locally. Here is the code snippet:

[2024-05-07 10:38:28]-[Thread-1]-[eureka_client:633] WARNING: Eureka server ["http://discoveryserver.kowri.uat:8080/eureka/"] is down, use next url to try.

Any sort of help will be very appreciated!

What if you use curl to visit http://discoveryserver.kowri.uat:8080/eureka/ ?

AAyiku commented 3 months ago

It is an internal link, so it can't be accessed locally

AAyiku commented 3 months ago

@keijack would the library be able to connect to a proxy server, that gives access to a the discovery server?

Currently no, pythone-eureka-client cannot connect to a eureka server via a proxy server, however, you can define your own HttpClient to do it.
