What issue do you have?

Hi,
I started the Joplin server from the official docker image. I enabled encryption on the clients. After inserting a note attachment and syncing, I create a second, test profile. I log into the server, then enter the key set in the first profile. The note opens correctly, but when I try to open the attachment, I get the message:
Cannot transfer file: Forbidden
