## Symptoms

- * Mobile Access Portal Agent is installed repeatedly when user accesses SSL VPN portal from Microsoft Edge browser
* Microsoft Edge browser gets stuck during launch of other SSL VPN portal applications: Compliance Scanner, SSL Network Extender or Secure Workspace
* In Windows Developer Tools, user may see the following error:  
  `"SCRIPT7002: XMLHttpRequest: Network Error 0x2efd, Could not complete the operation due to error 00002efd."`

## Cause

Microsoft Edge browser cannot communicate with Mobile Access Portal Agent listening on TCP port on localhost.

Early versions of Windows 10 had an issue when the Edge browser was not able to connect to localhost. Later, Microsoft added the checkbox which allows the browser to access localhost, but there are still complaints that Edge cannot access sites through loopback, for example:

Microsoft states it is by design *for extensions*. (Sort of isolation of Metro applications from other applications.) But it seems to be relevant for general browser tabs, as well as for extensions.
