Hi @pike
I only switched to Strato because I have the same problem with pCloud as you.
Even with the help of the pCloud support there it is not solvable, they simply claim - we have no issue, all systems work fine.
WebDAV with Strato woks fine (apart from this error message, I do not see any effects. The backup is saved well), but I’m reluctant to use WebDAV, I’d much rather use SFTP. However, SFTP does not come up, although a connection with a smp,en ftp client works.
@pagaille had comparible issues and wrote
But I can’t interpret what “Nethserver’s backup module expects the target server to be smart and will not work with dumb, basic, passive, restricted, pure (S)FTP servers” means to confront Stratos Support with concrete requirements in their SFTP server.
Box.com isn’t an alternative.
Edit.: sorry, I just realize that I have moved from the WebDAV problem to the SFTP problem.
