Hi @Evaristus_Adimonyemm,

Do you mind give us some more detail? What application are you trying to deploy? What route is giving you this error? What application is bound to it?

I deployed a springboot application to the platform, everything is working well, all health checks are passing, but whenever I click on the exposed url, I get that response.

I even tried appending the server context in my springboot app, but it still gives the same result. Normally, I have swagger and some endpoints permitted in my spring security, so, when you try to access the endpoints, it shows up (for local deployment though), but it doesn’t behave same with the url
