Cannot reproduce myself. Please give more details

Also looks good in my IE11 on Windows 10.

[tagliala]

thanks everyone

Cannot reproduce. Closing here but feel free to comment if you have news

[rkg-mm]

I can reproduce on a Windows 10 tablet with IE 11 in Edge mode.
Dev console fires
"CSS3111: @font-face encountered unknown error." and no icons are shown.

No idea why this could happen...

edit: however: I cannot reproduce on a Windows 10 VM in IE 11 using Administrator account
edit2: Since I'm on a company network this may be related to this Group policy: http://stackoverflow.com/questions/33023461/ie-11-error-css3111-in-my-own-code-and-google-com-fonts-doesnt-render-any-fon/34070604#34070604 I'll ask my IT if this policy is enabled

edit3: Yes in my case this Windows 10 group Policy called "Untrusted Font Blocking" was active.

@rstmm thanks!

@iflyfei could you please check?

[iflyfei]

maybe it causes by windows group policy not sure

[jwellsnh]

In my situation, a windows group policy was the cause. See this TechNet article:

Block untrusted fonts in an enterprise

@jwellsnh could you please update Troubleshooting Guide?

With Windows Firewall stopped (from services.msc), fontawesome doesn't work. If I turn on the service it works. This happens only on IE.
(Sorry for my bad english).

Cannot confirm, it works for me (Win10x64 / IE11 / Windows firewall manually stopped under services.msc)

[diegosanz]

Sorry, I searched more and I finally find this, so it's already reported.
Thank you for your time.

Is that a default setting under some versions of windows 10?

Is that a default setting under some versions of windows 10?

In my computer, the "block untrusted font feature" it's not stablised because I don't have any key on my registry called MitigationOptions in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Kernel\. Like this, with Windows Firewall running, Fontawesome works perfectly on IE11.

I cannot confirm because I only use Windows on my work, but I think that this is the default setting. In my case, the problem appears when I join into the domain of my company that, I don't know why, it stops the service of Windows Firewall and Fontawesome doesn't works.

[tagliala]

maybe this is a group policy option which does not apply outside domains

[tbinggeli]

I get this error too. Even when looking at fontawesome.io/icons.

I have brought this up before, but I am still unable to resolve the issue.

I know this is an old issue, our organisation came across this so could possibly help some one else. This bug would only affect IE11 for us on any OS. It would work fine over http but over https it would play up. We resolved it by commenting out the Pragma from within the web config of the website. I believe this would then allow for caching.

@Qore5 thanks

This case is also documented in our troubleshooting guide: https://github.com/FortAwesome/Font-Awesome/wiki/Troubleshooting#im-hosting-fonts-on-my-server-and-icons-dont-show-up

It does not strictly depend on IE but the way fonts are serverd is also involved

As posted in #8825
We had a customer with this problem. The solution was to make sure that fontdrvhost.exe isn't blocked by the antivirus software (in this case Trend Micro OfficeScan was the culprit).

Issue reproducible on (MCC-469654):
