I experienced a very similar bug today.

While retrieving a rather large file from a remote git repository my internet connection broke down such that the ssh connection stalled. I noticed this and killed the transfer on my side. After the connection was up again I restarted the transfer and got the following output:

  Unable to access these remotes: origin

However, I could retrieve any other file from origin. The problem was that git-annex-shell was still running on the remote side and therefore preventing me from fetching the file and only this file. Once I logged into the remote server, killed the still running git-annex-shell, \"git annex get\" behaved as it should and fetched the file.

However, there is definitely room for an improved error message which at least gives a hint what the problem could be. Of course, the best solution would be if the file was simply transfered.
