Why are only some apps connecting to their networks, while others don't and they just quit?

[Windows Central Question]

Some apps don't connect to their networks anymore and just quit.

I seem to have an issue on my Lumia 1020 running WP 8.1 Update with certain apps that I've had for awhile, specifically Trainr and Hanyu.co. The apps work fine for awhile, but suddenly they just stopped working. I'm not sure if it's because of my phone or because of the apps.

Both apps require logins and connect to a server. With Trainr, I get an error, "Cannot connect to server." With Hanyu, the app opens to the splash screen and then quits.

I thought it just might be the apps individually, but considering that this has happened to two apps, I'm starting to suspect it's something else. I've restarted/shut down my phone multiple times but nothing seems to help and the apps just don't work anymore, which is a shame since I really like both.

Is anyone else having the same issue? Does anyone know a solution? Thanks!

I checked Trainr in the appstore to see what the app was, it looks like a lot of people are having the same trouble with the app, just from the reviews on the homepage.Trainr | Windows Phone Apps+Games Store (United States)

I'd say it's a problem with the apps, not your phone.
