the duplicate "remote_addr" variable in /app/openResty/nginx/conf/conf.d/web.conf:153

The `remote_addr` variable in the `/app/openResty/nginx/conf/conf.d/web.conf:153` context typically refers to a configuration setting in Nginx, an open-source web server. `remote_addr` is a built-in variable that holds the IP address of the client making a request to the server. If you see it duplicated, it means that there are two or more instances of this variable at line 153, which might be unintended.

This could indicate one of the following issues:

1. **Redundancy**: The duplication may be a mistake and can lead to confusion or unexpected behavior if both occurrences have different values or settings attached to them.
2. **Intentional override**: It could be a deliberate attempt to set different access control rules based on different `remote_addr` values. However, this should be done with caution, as it could create complexity and might be better handled through conditional statements.
3. **Configuration conflict**: If the variables have conflicting directives, like one trying to set a default value and another overwriting it, it could cause problems during runtime.

To resolve the issue, you should review the exact content of the `remote_addr` lines and determine whether they serve a purpose or are unintentional duplicates. Ensure that there's no redundancy, logic errors, or conflicts in your configuration. Here are some related questions to help you investigate further:
