I have a small problem(at least I think that is small) with my phone Nokia C6-00. When I'm on internet with the browser(I noticed first on Facebook and now it started on every page) after 2 minutes on internet no matter if I'm connected wireless or from my mobile provider first it requires some certificates and I press always allow and after that it says no internet. When I'm resetting the browser,the phone it self restarts. It also happens with games and apps that need internet. It uses Symbian and I don't know what to do. My friends tell me to get Samsung or LG but I want to keep up with this phone because I will never find a phone like this with qwerty keyboard on slide and most of all... I love your phones. My first phone was 3110 and now I'm with c6-00...
Any help with this.
Hi @jason_brody ,
The expired certificate problem for Symbian phones is a major issue, and it gets worse in the future. There is a collection of updated certificates on http://www.traud.de/ta/ - The GlobalSign_Root_CA expired on my N8 and C7 some months ago.
I'm not sure if it'll make a difference with the phone restarts, and it's a nerdy procedure, but here goes:
In settings, phone, phone management, security settings, certificate management (or there about, it's the C7 in Danish I'm checking!) - find the list of certificates, tap each one to check if it's valid. If it shows an error, check the list on the traud.de website if there's a replacement. If so, download it to somewhere on the phone, delete the expired one (tap and hold to bring up the delete option), then find the downloaded replacement in the Files manager, and double tap to install.
Do not delete unless there is a replacement ...

In the case of
is the culprit because the administrator of your web-service did not install the complete certificate chain. Therefore, your Nokia did not trust Facebook anymore. Therefore that warning message.
@Kakoproject I updated my post above to clarify the situation. You should delete this Yahoo certificate and install the DigiCert one, that one is the current root authority for Yahoo Mail SMTP. Your issue was not related to GlobalSign. Anyway, if you follow the procedures above, your phone is ready for today again. Did that help?
