us.battle.net Connection Not Trusted.

When I try to connect to https://us.battle.net (World of Warcraft). I get connection not trusted. But only on this laptop, my desktop will connect. So far just battle.net has given me this error, I can connect to other https:// sites.

error info; us.battle.net uses an invalid security certificate.

The certificate is not trusted because no issuer chain was provided.

(Error code: sec_error_unknown_issuer)

It can't be a default setting as my other computer loads fine. and yes, I have read many posts, even the system clock idea. My clock is right on with the current U.S. pacific time.

Hey, looks like Blizzard or Digicert finally fixed the broken link. Run the site test and it shows it's working.

I checked and no more untrusted site error from us.battle.net, and no more black box when clicking the quick sign in.

Re: us.battle.net Connection Not Trusted.

The us.battle.net server doesn't send all required intermediate certificate(s).

You can inspect the certificate chain via a site like this:

You can copy the "DigiCert High Assurance EV CA-1" certificate text to a plain text file and import the file in the Certificate Manager.

  • Tools > Options > Advanced : Encryption: Certificates - View Certificates: Authorities

Do not check off any of the boxes on the import confirmation pop-up as those aren't required for intermediate certificates.

Re: us.battle.net Connection Not Trusted.

Thank you for the reply, I may have read a similar fix, but I'm wondering if there isn't a setting or fix that doesn't involve downloading and importing files yourself.

As I said, one computer using FF 14 will connect and have the info while this laptop wont. For the life of me I can't figure out why one works and not the other.

can anyone see the trouble shooting I've done so far? O.o If not, I tried an add-on called "cocoon" it's a proxy privacy tool. If I use cocoon, battle.net will load. also I was wondering if Norton internet security may have changed the way FF gets the info for a certificate. I disabled Norton and still couldn't get battle.net to open though. Just a guess because my other computer is using Avast.

Re: us.battle.net Connection Not Trusted.

It is a problem on the server and it should be fixed on their side.
You only see this error if you have never visited a website before that has send this intermediate certificate because Firefox stores them in the cert8.db file and use them automatically if needed (I didn't have the SSL error).

You should contact the website and inform them of the incorrect server configuration.
They can verify the SSL chain via the DigiCert test site.

Re: us.battle.net Connection Not Trusted.

sadly this problem has been posted a few times on blizzard forums. however because the admins don't get the error they seem very reluctant to admit anything is wrong.

I did successfully visit battle.net using cocoon, but when I turn it off, FF still errors. Is this part of the private browsing feature? even certificate info isn't being saved?

Re: us.battle.net Connection Not Trusted.

You can easily reproduce the error in Firefox if you (temporarily) remove the cert8.db file or use a new profile or delete the intermediate "DigiCert High Assurance EV CA-1" certificate in the Certificate Manager.
