Same issue with the Windows version of Adept.
I get the message:
<Error>
<Code>AccessDenied</Code>
<Message>Access Denied</Message>
<RequestId>B5K38N5AE445WCR0</RequestId>
<HostId>1Ti8WdYpmXA6KYkVvgsgG2cTYRZ+YDMyiNpOnHDf5wDC32TUniwlhZmJlOIXDmjAXwT/VeOtxts=</HostId>
</Error>
I have tried disabling both virus checker and VPN, along with using a different browser.
