FileZilla Forums

Hi, I purchased FZ Pro in order to connect to S3. I set up my account a few months ago, and was able to connect. However, when I try to connect now (without changing any info), it gives the error:

Error: 'S3 - Amazon Simple Storage Service' is not a supported protocol.

Which is weird, because why give S3 as an option if it is then not supported? Did anything change recently?

You have started regular FileZilla, not FileZilla Pro.

I don't think that's the case. I do see the "S3" option when adding a new connection, which afaik doesn't appear in the regular version.

I have always used Pro before, and haven't reverted back for any reason. S3 connections have worked for me in the past, but suddenly stopped working. Did any settings change or are required now while they weren't before? The error message is unclear so I don't have a clue how to fix it.

Check the title bar in the main window, does it mention Pro? Yes: It's FileZilla Pro. No: It's not.
