# Troubleshooting Guide

{% hint style="danger" %}

### <mark style="color:red;">**The BastionZero product is maintained for existing BastionZero customers only.**</mark>&#x20;

Moving forward, we are natively rebuilding BastionZero’s technology as Cloudflare’s [Access for Infrastructure](https://developers.cloudflare.com/cloudflare-one/applications/non-http/infrastructure-apps/) service.

## Curl Upload

If you're seeing this error message:

`curl: (26) Failed to open/read local data from file/application`

Run the command again with `-v` and you will see a more verbose output. This error can arise from the below web proxy size limits and will result in a code 413: Request Entity Too Large.

### Web Proxy Size Limits

| Size  | Description             |
| ----- | ----------------------- |
| 10MB  | Request Body Size Limit |
| 150MB | File Upload Size Limit  |
