Unable to configure filesync or connect via SSH

[matifali]

While trying out Fileync in v0.3.0, It always fails with this error.

I have tried,

1. Quitting and Restarting Coder Desktop
2. Uninstalling and Reinstalling Coder Desktop
3. Logging Out and Logging back in

Additionally, I am using the latest Coder CLI, which has the SSH suffix changes for config-ssh.

So I tried coder logout, and the error updates to,

This makes me think that Coder Desktop is trying to use the CLI instead of the Coder Connect tunnel.

Here is the relevant ~/.ssh/config snippet

# ------------START-CODER-----------
# This section is managed by coder. DO NOT EDIT.
#
# You should not hand-edit this section unless you are removing it, all

I was able to reproduce a similar issue running Coder Desktop v0.3.0, and with an SSH config applied by the CLI running v2.21.0-devel+f2fb0caf4. I was only able to reproduce an issue when creating a file sync session against a workspace for the first time, where the Mutagen agent binary needs to be copied across, which might take some time.

Against a workspace with the agent binary already installed, I found no issues.
