How To Fix an SSL Certificate Error on Android

Table of Contents

Your SSL certificate verifies your server identity and encrypts all of your Internet traffic safeguarding all your data. SSL is designed to provide a secure connection between servers and web browsers or between two applications – like Skustack and your devices.

In order to keep all your data secure your SSL certificate needs to be up to date. When your browser fails to validate your certificate the system will display an invalid certificate error, warning you that the connection may be insecure.

How this certificate error may show up for you: 

  • You get a security warning
  • You get an in-app error message: “Check your internet connectivity. Your wifi may be turned off or your Webservices may be temporarily down. ERROR 6001”
  • You can’t access the Skustack app at all
