AWS use one way only?

When I try to upload new sermon to AWS through "Create new sermin" feature in SS, I get "rec_20170618-1240_cleanfast.mp3 (30.3 mb) » Error: COM_SERMONSPEAKER_FU_ERROR_UNABLE_TO_UPLOAD_FILE", but when I upload the message into the bucket directly, I can't pick it in SS backend - simply don't see it. Do I understand it right that AWS works one way only? Or there's something wrong with settings? Did I google correct information that public key and secret key are simply bucket login and password? Or it's something different? Trying to navigate through endless AWS features, options and gimmicks, I've cracked my skull in two already - can't figure out how to set it up and where exactly do I get those keys... (((

public and secret key have nothing in common with your user and password. That's why it doesn't work

To create/get those keys, you need to select "My Security Credentials" in the dropdown at the top where you also can access "My Account" and the like. There you will see a slider "Access Keys". There you can create those keys and then copy into the SermonSpeaker options

Sorry to have to bother you again, though it still doesn't work: yadi.sk/i/hBlNuQy03KQ29n I've set the settings, and "Create Sermon" still doesn't connect to AWS... Any more advice?

Could this be the reason? yadi.sk/i/acr-VFhC3KQ2kE If so, how do I fix it?

Yep, that could be. Can you tell me which region your bucket is in? Then I can try to replicate it.
