# Diagnosing problems If you are having problems with nginx-le we provide some hints and solutions to common problems. ## Welcome to nginx! When you connect to nginx-le you get the nginx welcome page rather than your actual web site. Nginx-le typically uses two configuration files that tell nginx-le how to connect to your web server. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://nginxle.onepub.dev/diagnosing-problems.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
