Having trouble setting with Retrospect 15 with Backblaze B2

[vicorly]

Hello folks;

I'm having trouble setting up Retrospect 15 with Backblaze B2. If I don't put in the bucket name, I can login, and then Retrospect tries to create a bucket with the name "retrospect-XXXXXX" where XXXXX is my Backblaze account ID... but I get the error:

Access denied by cloud service. Bucket names must be 6 to 50 characters long and only contain upper-case letters, lowercase letters, numbers and hyphens.

Any ideas?

Thanks

Victor
