What causes HTTP 405 error?

The HTTP (HyperText Transfer Protocol) 405 error points to the fact that the request method has been recognized by the accessed servers, but the target resource is not supported.

This error can occur for a variety of different reasons, but the most common is that the server you’re trying to access is configured in such a way that it doesn’t allow you to complete a specific action for a specific URL.

How do I fix the HTTP 405 error?

1. Try using another browser

For a start, try opening Instagram in another browser than the one you are currently using.

opera instagram sidebar

Our recommendation would be Opera due to the integrations it has with various social media platforms, Instagram included.

This guarantees a faster connection to the respective platform, plus instant access via a dedicated icon that can be added to the browser sidebar.

If you have not used Opera before, download it using the button below (it only takes a couple of minutes), then open the Settings menu.

Scroll down to Sidebar and check the box next to Instagram (or any other element you want to add to the sidebar, for that matter).

Then click on the Instagram icon and log into your account as you’d usually do (save your credentials if necessary).


With Opera’s smart social media integrations, you’re just one click away from your Instagram feed.
