Currently, I am building a website with Streamlit with the configuration below, but due to a WebSocket error, it does not transition from the “Please wait” screen.
Could you please advise me on how to handle this?
- AWS-Cloudfront -(HTTPS)-> 2. AWS-ALB -(HTTP)-> 3. AWS-NLB -(TCP)-> 4. EC2
With access to 3. NLB and 4. EC2, the WebSocket is correctly connected and the expected screen transition occurs. With 2. ALB, I am not sure what the cause is, but it cannot connect.
- Cloudfront, as mentioned above, displays up to Streamlit, but due to a WebSocket error, it does not transition from the “Please wait” screen.
If anyone understands how to handle this situation based on the information above, please instruct me.
Additionally, I am path routing with /xxx/yyy on 2. ALB. The browser I am using is Chrome.
