Example URL:
https://login.etadirect.com/atni1.test/m

Steps to reproduce the problem:
Very Important: to reproduce, User Agent of the webview to be set to diff string than existing string. For example,
webviewSettings.setUserAgentString = "Vmware Browser version"
Login to this site: https://login.etadirect.com/atni1.test/m (external)
Username - e9901196
Password - gtt12345
The page does not loads properly rather "Network Instability Detected" is shown. 

What is the expected behavior?
The prob only exists with Webview and not on Chrome browser. 
1. To re-create the prob, create webview and modify the UA field to something else. In Vmware browser case, UA is appended with (Vmware Browser version). This causes the below url to load with "Network Instability Detected" error. 
2. If same webview is used without modifying the UA then the site works fine and shows proper page

What went wrong?
Modifying the UA field causing webview to show error which is not thrown from the server because we analyzed server response on both success case (UA not modified) and error case (UA modified)
