Fabric says 'no route to host', even though I can access it over SSH

I'm having some issues uploading a file to a server with Fabric. I get the following output:

Fatal error: Low level socket error connecting to host ssh.example.com: No route to host

Aborting.

The weird thing is, when I connect manually using ssh (same host string, I copy-pasted it from the fabfile to make sure), it works perfectly as expected. I can also use scp to copy the file to the same location manually.

The offending line in my Fabfile is this, if it helps:

put('media.tgz','/home/private/media.tgz')

Also, I'm connect开发者_JAVA技巧ing to a different host to the rest of my fabfile using the @hosts() decorator (this particular method uploads static media, which is served from somewhere different to the app itself).

I had the same issue. Had not investigated it but using the IP-Address instead the hostname helped. This particular host had an IPv6 AAAA record but my client had no IPv6 connection, maybe this is the reason. HTH
