[D] If using a reverse proxy and finally accessing it with a domain name, some pages would report errors when accessed [superset]
GitHub user zsw4579 created a discussion: If using a reverse proxy and finally accessing it with a domain name, some pages would report errors when accessed
### Bug description
When I was deploying superset to the production environment, using a reverse proxy and finally accessing it with a domain name, some pages would report errors when accessed, but some pages were correct. What should I do to solve this problem?
### Screenshots/recordings
### Superset version
master / latest-dev
### Python version
3.11
### Node version
18 or greater
### Browser
Chrome
### Additional context
_No response_
### Checklist
- [x] I have searched Superset docs and Slack and didn't find a solution to my problem.
- [x] I have searched the GitHub issue tracker and didn't find a similar bug report.
- [ ] I have checked Superset's logs for errors and if I found a relevant Python stacktrace, I included it here as text in the "additional context" section.

To address the "400 Bad Request" error you're encountering when accessing Superset through a reverse proxy with a domain name, you can try the following solutions:
1. **Ensure Correct Header Configuration**: Make sure your Nginx configuration is correctly setting the `X-Forwarded-Proto` header to reflect the scheme used by the client. This helps in generating accurate URLs in redirects. Update your Nginx configuration as follows:
```nginx
proxy_set_header X-Forwarded-Proto $scheme;
```
2. **Enable Proxy Fix in Superset**: In your `superset_config.py`, enable the proxy fix to correctly interpret headers set by the reverse proxy. This is crucial for accurate URL generation in the 'Location' header:
```python
ENABLE_PROXY_FIX = True
PROXY_FIX_CONFIG = {"x_for": 1, "x_proto": 1, "x_host": 1, "x_port": 1, "x_prefix": 1}
```
3. **Check Redirect Configuration**: Ensure that the `Location` header in HTTP responses is correctly configured to use HTTPS. This can be managed by ensuring the `X-Forwarded-Proto` header is set correctly, as mentioned above.
These steps should help resolve the issue with incorrect redirects and the "400 Bad Request" error when accessing Superset through a reverse proxy <sup>[[1]](https://github.com/apache/superset/discussions/32757)</sup><sup>[[2]](https://github.com/apache/superset/blob/master/superset/config.py)</sup>.

The "400 Bad Request" error you're encountering is likely due to misconfigurations in your reverse proxy setup, specifically related to handling HTTP and HTTPS requests. Here are a few steps you can take to resolve this issue:
1. **Check Nginx Configuration**: Ensure that your Nginx configuration correctly handles HTTPS requests. A common issue is incorrect headers, such as `X-Forwarded-Proto` and `X-Forwarded-Host`. Make sure they are set properly:
```nginx
proxy_set_header X-Forwarded-Proto https;
proxy_set_header X-Forwarded-Host $host;
```
Avoid including 'https://' in the `X-Forwarded-Host` header, as this can lead to redirect issues <sup>[[1]](https://github.com/apache/superset/discussions/32757)</sup>.
2. **SSL/TLS Configuration**: Verify that SSL/TLS is correctly configured in your reverse proxy. Ensure that the server block handling HTTPS requests is properly set up with the necessary SSL certificates.
3. **Redirects and Protocols**: Check if there are any redirects in your configuration that might be sending requests to HTTP instead of HTTPS. This can cause the "400 Bad Request" error if the server expects HTTPS.
4. **Superset Configuration**: Review Superset's configuration settings related to HTTP and HTTPS handling. Ensure that any settings related to protocol handling are correctly configured to match your reverse proxy setup <sup>[[2]](https://github.com/apache/superset/blob/master/docs/docs/configuration/configuring-superset.mdx)</sup>.
By addressing these areas, you should be able to resolve the "400 Bad Request" errors when accessing Superset through a reverse proxy.
