Login problem on Android

I cannot connect to the server on my android phone. Mattermost works well on PC and iOS, except Android. I am using the latest app version and my phone is Mi 5. All my friend using Android have the same problem. Somebody helps me to resolve this?

Hi @Hongchen!

Thank you for reaching out.

Can you help take a look at this troubleshooting doc for tips?

Can you also try reinstalling the app to see if it helps?
