**400 Bad Request**
======================
When you visit a web application like Bizmaker, the internet protocol version 4 (IPv4) connection is established between your device and the server hosting the website. However, if there are issues with the request being sent over this connection, it will result in an HTTP 400 Bad Request error.
In some cases, errors can be resolved by switching to a different method of communication - namely, the internet protocol version 6 (IPv6) connection. This process is known as a "switching from HTTPS to HTTP." Here's how you can resolve the issue:
**Understanding the Error Code**
-------------------------------
When an error occurs due to a mismatch between the requested and sent methods, it results in an HTTP 400 Bad Request status code. This indicates that the server does not recognize the request and cannot process it.
**Steps to Resolve the Error**
---------------------------
To resolve this issue, you need to update your web application to use HTTP instead of HTTPS for any URLs containing a query string or a parameter with special characters like `&`. For example:
* If you have a URL that includes a query string, change `https://www.bizmaker.org/2-insight-cct-carrum-downs-vic-3201-australia/business-services/fix-it-right-plumbing-melbourne?param=value` to use the following format:
```http
http://www.bizmaker.org/2-insight-cct-carrum-downs-vic-3201-australia/business-services/fix-it-right-plumbing-melbourne?param=value
```
* If you have a URL with special characters like `&`, change `https://www.bizmaker.org/2-insight-cct-carrum-downs-vic-3201-australia/business-services/fix-it-right-plumbing-melbourne¶m=value` to use the following format:
```http

```
**Additional Tips**
----------------------
To avoid this issue, it's essential to use HTTPS for all URLs in your web application. Also, if you're using any third-party libraries or frameworks that rely on HTTPS, make sure they also support HTTP as an alternative.
**Conclusion**
----------
In conclusion, understanding how to resolve the 400 Bad Request error is crucial for building reliable and secure web applications like Bizmaker. By switching from HTTPS to HTTP for specific URLs with query strings or parameters containing special characters, you can ensure that your application receives the requests it needs to function correctly.
