Hello all,

I keep getting the following error on my site:

Failed to connect to '' with status code '503' and reason 'Site Unavailable'

Why does this happen?
Please let me know which more information do you need to understand the reason.

(I am sorry if I chose the wrong tag below. I didn't know which one was the best fitted...)

    Hi @dushkin ,

    First, I would enable application logging for your Spring Boot application; I'm assuming. The HTTP 503 against the kudu, you can also try some of the recommendations on to see if there was a deployment issue. Feel free to comment below if you need any further assistance.
