I'm trialling TheBrain (and enjoying it)... one feature that I'm very keen on is the use of WebBrain so that my personal brain and work brain can be one and the same.

But I have a problem at work, which sits behind a firewall that is also port limited: TheBrain just does not connect to WebBrain (just sits there... no error message).

I've tried it downstairs in IT on an 'external' computer and TheBrain is up and running very quickly.  At my desktop there is no connection though.

My question: What are the requirements for TheBrain to be able to communicate with the WebBrain server?

Thanks (if it's a port that needs to be open then that's going to be an argument with IT)...
I found this in the documentation: 
Port 443 is used for encrypted syncs.

Is there anything else that may be blocking the connection?
If you are having trouble connecting to TheBrain Cloud Services, please ensure that your firewall allows TheBrain.exe to communicate with the WebBrain server at over the standard HTTPS and HTTP ports (443 and 80).
By default, synchronization is protected using 128-bit AES Encryption on port 443. This is the same encryption used by the US government to protect classified information. If your firewall does not enable an SSL connection, you can disable encryption and use port 80 by navigating to TheBrain Preferences, General tab, and then replacing '' with '' in the Server address field (if no protocol is specified, the default is https).
It is also possible that your company's Firewall and/or proxy is causing your sync issue.
* Try disabling the firewall on your local machine.   
* Double check with your IT staff of to see if your internet connection is modified
* If your IT staff is using a firewall, you can ask them to add to the white list of your company's firewall.
* If your IT staff is using a proxy, you will need to try setting up a Proxy connection via TheBrain by using the following steps:
1. From the TheBrain 7 login screen, click "Server & Proxy Settings"
2. In the next dialogue, leave the server address as "" and click "Proxy Settings"
3. In the Proxy Settings Dialogue, Click the checkbox next to "Use a Proxy Server"
4. Enter all of the following information, including your proxy address and port
5. If your server requires authentication (ask your network admin/IT), check the box next to "proxy server requires authentication" then, fill in authentication information, including your username, password, and domain
Please verify your settings with a network admin and let us know if you still experience issues.
Being worked on by IT... thanks
