Lightning Community Failed to initialize a component - IE

We have recently developed a new community with lighting components on it. This community works perfect on all the browsers, but on IE 11 (11.0.90) it fails on the landing page component.(It only show standard loading screen)

When i opened it in community builder in IE it says:

Error ID: 1960994957

This page has an error. You might just need to refresh it. Failed to initialize a component [Expected ':'] Callback failed: serviceComponent://ui.comm.runtime.components.aura.components.siteforce.controller.PubliclyCacheableComponentLoaderController/ACTION$getPageComponent Failing descriptor: {siteforce-generatedpage-ce00a3fa-6452-4398-9cc2-0e630449a95f.c1550051805662}

Do anyone know whats going wrong?

Hi Nikhil,

Greetings to you!

According to Salesforce:

Support for Internet Explorer 11 to access Lightning Experience is retiring beginning in Summer ’16.
  • You can continue to use IE11 to access Lightning Experience until December 16, 2017.
  • If you opt into Extended Support for IE11, you can continue to use IE11 to access Lightning Experience until December 31, 2020.
  • IE11 has significant performance issues in Lightning Experience.
  • It is strongly recommended that you do not use Internet Explorer 11 with Community Builder.
  • This change doesn’t impact the Salesforce Classic.

You must 'opt in' for it to work today in IE11, but know that that will save you only until the end of the year 2020.

How to opt in?
The opt-in option will become available only when your org updates to Winter '18 version. Once that happens, go to Setup, enter "Session Settings" in the Quick Find box, then select Session Settings. Scroll to the section titled "Extended use of IE11 with Lightning Experience" and agree to terms.

@John.

I actually don't remember what i did change to solve it. Currently we are not facing any issues.
May be you can start with removing some custom lightning component or VF from the community? And make sure to upgrade the community by going into setting.
