Hi Jennie,
We don’t currently support connecting through a proxy server yet. Some people find that some requests work (e.g. if not uploading or downloading anything, you can see your files, etc.), depending on their proxy environments and such, but that may lead to some false hope since it won’t work as expected.
There’s an outstanding feature request for it here in this other thread:
Sorry we can’t help in your current situation. If you stop using a proxy to connect from home, that could help, but I realize that you may need to connect via proxy for other reasons. It’s also possible we may be able to support it in a future release, but there’s no estimate for when that may become available.
Best,
-Jeff
