Backblaze B2 with specific bucket not working

[Jake Godding]

I'm attempting to connect to my Backblaze account and if I create a key with access to only a specific bucket for security reasons I am unable to connect due to an error citing Security Error. This happens if I specify the name of the bucket or not in the connection

The documentation in the above link is really out of date - please help us all by updating this. Thank you.

After a lot of trial and error...

 

To connect:

I could only get this to work if I made a key which provided access to ALL BUCKETS.

In the connect box:

Username - B2 Email Address
Account Id - "keyID" from Master Application Key
Application Key - "keyID" from your newly generated B2 key 
Application Key ID - "applicationKey" from your newly generated B2 key
