To verify if you are in this last situation, fire up a web browser and try to visit your website by using a different IP adress. You can accomplisch this by e.g. disabling your mobile phone Wi-Fi, and accessing your website over the 4G network. If your website loads just fine, read on…
Now, you’re thinking, how can using an app to connect to my website trigger this behaviour? This has to do with the protocol it uses to communicate: XML-RPC. This protocol is very useful for remote website control, but has, over the years, also gained a lot of attention from hackers.
Subsequently, a lot of webhosting companies implemented protection against the use of the XML-RPC protocol. This means, their algorithms will detect any XML-RPC usage and block the originators IP adress.
First of all, you should realise there is nothing wrong with your website. It’s (just) your IP adress that is blocked from accessing it!
All that’s left to do is to contact your hosting provider, explain them the situation, and ask how your IP adress can be unblocked.
A detailed article about XML-RPC background is available here. By the time you found this article, you’ve probably read it already 🙂
