Recently set up a new client with Duplicati the way we’ve been setting up most of our clients, on a B2 bucket, backing up whatever important server files the client has directly from their server. It’s failed around 5 times in a row now and I cannot figure out what is causing this issue. It keeps saying connection was forcibly closed, but does this mean there’s an internet issue or something? Most everything is default settings, smart retention and a timeout value of 5 minutes, and yet it keeps failing in a concerning way. Logs posted below.
