If you are using a custom proxy in Expandi and would like to test that it is working, you can do so using the following steps.
Install chrome extension Oxylabs Proxy Extension
Click add a new proxy and fill in the details of the proxy you want to test
3. Click connect to connect the proxy. When it is succesful there will be a tick beside it (see above image)
4. Open a new tab in your Google Chrome browser and go to https://lumtest.com/myip.json
If in there you see the IP you have added then the proxy is working. See below as an example of a working proxy.
If you do not see your IP above, or are still unsure what to do, the best thing to do is contact your proxy provider who can help you move forward.
