AGOL organizational page not loading in IE - local storage error

[BillDaigle]

I have several users who can't seem to access our AGOL organization account on IE11.  Other users can get to it just fine.  The difference appears to be associated with security settings.

The path to our AGOL site is http://mtfwp.maps.arcgis.com​.

Other organization pages behave the same way:  http://fema.maps.arcgis.com/

• http://fema.maps.arcgis.com/
• http://launceston.maps.arcgis.com/​
• http://uplan.maps.arcgis.com/

When the problem occurs, the page just comes up blank with no indication of the problem.  I was able to track down the fail point using the developer tools. 

The "Access is denied" error stops the rest of the script from running.  The script that fails is http://cdn.arcgis.com/cdn/xxxx/js/arcgisonline/base.js.

When users call and report the problem, I have been telling them to add *.arcgis.com to their list of trusted sites.  But...it seems like the problem really needs to be fixed on the ESRI side, by putting the check for localStorage inside a try/catch.  Anyone from ESRI (Courtney Claessens, Daniel Fenton) willing to chime in?

Try adding these to you "trusted sites".  This is needed for Pro to work too.

https://*.arcgis.com

https://*.arcgisonline.com

https://*.esri.com

https://*.virtualearth.net

https://ago-item-storage.s3.amazonaws.com

Not 100% these last two are needed for every user, but better to include than have to troubleshoot if/when they do.

Thanks Rebecca. That helps for users that call, but not when they get to a blank page and give up. It still seems like this needs to be fixed on ESRI’s end.

Ahh...the "public" I'm assuming.  Internally, our network folks were able to push out the trusted sites when they pushed the update last month to all our machines.  It seems to only be an issue within our firewall.  At home, I didn't have an issue.  But I understand it could be an issue for other users too.

[BillDaigle]

Yeah...the public .  Internally, we have some users that have the problem and others that don't.  I suspect the same is true for the public.
