"Connection time out", "No internet connection" and cloud sync error

[Martin]

Please help. I can't download any new games or updates onto my MacBook and keep receiving "Connection time out" or "No internet connection" errors. Downloads are not starting at all. Also, I'm receiving cloud sync errors.

I've tried:
- Testing my internet connection, which is fine. All other applications are fine. Steam client allows still allows me to browse the store etc.
- Changing download region
- Clearing cache
- Uninstalling and reinstalling Steam
- Ensuring Steam and OS are up-to-date
- Confirming firewall on my device are not blocking downloads. I'm connected to a home network, so shouldn't be blocked by any corporate policy.

Any more suggestions?
