Using the SFTP option when configuring a remote file server fails; From the sshd logs, we can see: Unable to negotiate with 192.168.255.255 port XXXXX: no matching host key type found. Their offer: ssh-rsa,ssh-dss [preauth]

OpenSSH 8.8 seems to have disabled ssh-rsa based authentication by default.

While this is relatively easy to band-aid, other SFTP apps (for example, termius) do not seem to suffer from this.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
