App loads things for a minute then won't load any other data

For the last month or so, every time I open the app it will load data for a minute or so, and then it loads absolutely nothing. Nothing will load until the app is restarted. Very annoying because I barely do anything until it stops and I have to restart it and get back to where I was before it stops loading again. It's like the connection to the server just times out after a minute or so.
