I'm trying to subscribe to some topics but I have issues because the Medium hub doesn't verify my intent - it doesn't contact my callback to have the challenge returned.
I've verified that the server is reachable and is responding, but no requests are coming through. Should I check something else?
And yes, the request for subscription did return 202.
Is the callback ok to be https?
Also some feeds can't be added at all, returning an error 422 with text Please provide a valid hub.topic (feed) URL that is accepted on this hub. This url could not be fetched. Even though it's a valid user. This happens even after correcting it to the url that the response tells me the topic has to be. For example I did a test with https://yieldguild.medium.com/feed and got response that the topic should be https://medium.com/@yieldguild/feed. But when I set this topic I get error 422.
