Removing of HTTPS security warning

Summary

One of the main benefits of HTTPS is that it adds security and trust. It protects users against man-in-the-middle (MitM) attacks that can be launched from compromised or insecure networks. Hackers can use such techniques to steal your sensitive information. Implementing SSL secures any data transmitted between server and browser during a user's session interacting with your device. This article will help you get a good idea about how to implement security into your network while using Teltonika devices.

Certificate creation and trust

1. You must have a DNS record linked to the IP of the router; in my case, I’m using a Windows server to act as a DNS server.

   As shown, I choose the hostname rut955.teltonika.uae and it's linked with 172.16.16.1 the LAN IP of the router.
   This hostname will be used for creating the certificate later.
