How to solve this problem ?

My nodebb forum is successfully done. But I have a question. My forum always says ‘Looks like your connection to NodeBB was lost, please wait while we try to reconnect.’. And admin board, too. Who can tell me how to solve this. My server system is unbutu 16.04. Thanks a lot.

Two main reasons this happened for me:

• url in your config is not configured properly. Thus you try to access your website over another URL than the one configured. If you've installed in a subfolder, make sure to access it at the subfolder location and add the subfolder to the url in the config.
• Your reverse proxy is not configured properly for web sockets. Follow the appropriate documentation.
