What version of iOS is your phone running?

8.1

I was unable to reproduce on iPhone 6 with iOS 8.1 and Appian App v2.6.0.

Is this occurring for all sites? Can you let me know the URL you've specified for the site on which you are seeing this issue (screenshot looks like its Appian Forum)?

Could you switch from WiFi to Cellular Data provider and check if you are still seeing this issue?

Based on the Error at least, it looks like your device is having problems connecting to the site.

Yes it's Appian Forum that I'm connecting to. The same error occurs from wifi and cellular connections. I will try deleting the app and reinstalling.

Deleting the app and reinstalling seems to have fixed it!
