    Server certificate error message when I go on FB via Phone


    Everytime I go on Facebook on my phone, I always get this error message: server certificate subject cn do not match domain name cn: a248.e.akamai.net CN:GTE CyberTrust Global Root. Before it popped up twice, but now it's three times, and recently it's now not just facebook but one other site that popped a similar message starting today.

    I don't know what this means, nor how to stop the error message from popping up again. So any help would be appreciated. If phone info such as type and model is needed, just ask.

    The first suggestion would be to uninstall and reinstall the facebook app. But I'm not good with phones :)

    Dunno how you update Facebook (I don't use it)

    it looks like updating Facebook on the phone will fix the issue (that's how it fixed Renee's issue!).

    Ahhh, I also see this error sometimes if the address in the address bar doesn't match the certificate address exactly. So if address shows as facebook.com, make sure you try www.facebook.com

I get a certificate error on every site that has a Let's Encrypt certificate. It happens in IE11, Chrome and Safari, so I'm assuming it's a Windows issue. I can still ignore the warning and proceed to the site, but it's very annoying as loads of sites use Let's Encrypt. Thanks for any...
