## You are experiencing one of the following issues

* [I can't send any requests through Postman. My network requires a proxy.](#h_01FG72AVF0WSKWQD6E2152A504)
* [I can't send any requests through Postman. My network does not need a proxy.](#h_01FG72B18ZEM6BXPW7DJ7MP54S)
* [I have a proxy that uses basic auth. I don't know how to make it work with Postman.](#h_01FG72B9GMYQSY0XWP993Q6S1J)

## How to unblock yourself

### I can't send any requests through Postman. My network requires a proxy

* Make sure you have  [added a proxy to your operating system](/help/faqs/sending-requests/how-to-add-a-proxy-to-the-operating-system) .
* Make sure you have [enabled the custom proxy option](/docs/getting-started/installation/proxy/#using-a-custom-proxy-for-requests) within Postman.

### I can't send any requests through Postman. My network does not need a proxy

Make sure you have **turned off** the system proxy.

If this doesn't unblock you, it may be because some environment variables are set up in your system.

You can either

* Remove the environment variables `http_proxy` ,  `https_proxy` ,  `HTTP_PROXY` , and  `HTTPS_PROXY`
* Start Postman with these *variables* turned off. See the following instructions below, depending on your OS.

#### Windows

Create a *postman.bat* file with the below content. Then, double-click this bat file to Postman without any proxy environment variables set.

```
set HTTP_PROXY=''set HTTPS_PROXY=''set http_proxy=''set https_proxy=''start C:\path\to\Postman.exe
```

#### Linux and macOS

```
http_proxy=''https_proxy=''HTTP_PROXY=''HTTPS_PROXY=''/path/to/postman
```

### I have a proxy that has basic auth. How to make it work with Postman?

1. Inside the proxy settings and under *Default Proxy Configuration* , tick the box *This proxy requires authentication*
2. Enter the **Username** and **Password**
3. Hit the button **Save and restart Postman**
