Android app with many users complaining cant connect on Wifi but works on mobile network

Question

I have an Android app on play store with about 500,000 downloads. Its a wallpaper app that retrieves all wallpapers from my server.

I have so many users giving negative ratings saying the app wont load walls on wifi but works on cellular network. here is one of the latest reviews

Doesnt work on wifi First day it works on wifi. Then. Suddenly stops working and doesnt load on wifi. Works good on mobile net. Please look into this.

I and my beta team have never had this issue happen on our devices or emulator.

This is the library im using com.mcxiaoke.volley:library:1.0.19

Looking at my crashlytic reports i see this is one of the top non-fatal issues

I have censored out the actual address.

What could be the issue? Could it be a issue with users wifi network they are on? or an issue with my webserver, which is DreamHost?

`"www.*****.io": No address associated with hostname` - just to confirm, did you censor the URL? — Bo Milanovich, Apr 06 '16 at 19:02
It definitely isn't an issue with your server. Its a DNS issue. Possibly the DNS hasn't updated yet if its a new server, or possibly its blocked by the ISP of that wifi. Have they tried on wifi at another location? — Gabe Sechan, Apr 06 '16 at 19:10
Well i personally cannot get the issue to happen. I only see user complaints in reviews. — BigDX, Apr 06 '16 at 19:14
