Hi @Ibrar Ansari, I'm an AI assistant for Novu. While a team member reviews this question, I'll see if I can find relevant sources for your question. ----------------------------- While I generate an answer, here are some sources that might be helpful: * Deploy with Docker * AWS * Run Novu in local machine * Object Storage (S3, Blob, GCS) ----------------------------- Answer Based on the .env configuration and nginx vhost setup you've provided, it seems like you're configuring Novu to work behind an nginx reverse proxy. The error "POST https://mydomain.com/api/v1/widgets/session/initialize 404 (Not Found)" indicates that the request to the API endpoint is not being routed correctly to your Novu service. The API_CONTEXT_PATH=api in your .env file suggests that your API should be accessible under the /api path. However, your nginx configuration for the /api location is proxying requests to http://localhost:3000/api. Given your setup, it's possible that the issue lies in how the context path is being handled by nginx or the Novu configuration. To troubleshoot this issue, consider the following adjustments: 1. Nginx Configuration: Ensure that the proxy_pass directive does not append the /api path again to the proxied request. This can lead to requests being sent to http://localhost:3000/api/api/v1/widgets/session/initialize instead of the correct http://localhost:3000/api/v1/widgets/session/initialize. Modify your nginx configuration like this:
location /api {
proxy_pass http://localhost:3000; # Remove /api here
...
}

location /api {
proxy_pass http://localhost:3000; # Remove /api here
...
}

This change ensures that a request to https://mydomain.com/api/v1/widgets/session/initialize is correctly proxied to http://localhost:3000/api/v1/widgets/session/initialize. 2. Environment Variables: Double-check the environment variables in your .env file, especially the $HOST_NAME variable, to ensure they are correctly set and accessible by Novu. Incorrect environment variables can lead to improper URL resolutions. 3. Context Path Configuration: From the information provided, it's not clear if additional configuration within Novu is required to fully support the API_CONTEXT_PATH. The official documentation does not specify detailed steps for configuring context paths within Novu itself for reverse proxy setups. However, the general guidance on reverse-proxy/load balancers setup suggests setting the GLOBAL_CONTEXT_PATH for the base path of the application and adjusting API_CONTEXT_PATH, WIDGET_CONTEXT_PATH, and WS_CONTEXT_PATH accordingly (1) . If Novu version you're using supports these environment variables directly for reverse proxy setups, ensure they are correctly set. Otherwise, handling context paths might need to be managed entirely by nginx. 4. Novu and Docker Configuration: Ensure your Docker-based Novu deployment is correctly set up according to the official documentation. Verify that the Novu containers are running and accessible on their respective ports (3000 for API, 4500 for widget service, etc.) on the host machine. If after making these adjustments, you're still facing issues, it might be beneficial to check the Novu and nginx logs for any additional errors or warnings that can provide more insight into the problem. Additionally, consider reviewing the Novu community discussions or reaching out for support for more specific guidance on
