For accessing the device WebaUI using HTTPS it requires a certificate, else it will show the below error:

In this example, we will be able to access the device webpage using HTTPs, with a free certificate from a free CA.

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 a 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.

2. Go to: GetAcert website.

3. Fill in the information regarding your requirements:

   NOTE: 1,2 and 3 are the names you want to use in the browser.
   Other information isn’t mandatory. Click Next Page.

4. Check the data once again, if everything is okay click Submit self-signed Certificate:

5. The final page:


6. Click on (+) beside Open Private Key:

Copy the text to a new Notepad file, and rename it to name.crt in my case I used a simple name cer.crt


7. Click on (+) beside Open Public Key:

Copy the text to a new Notepad file, and rename it to name.key in my case I used a simple name key.key


8. Click on the [.p12] file, and it will be downloaded:


9. Go to the Microsoft search bar and type: cer then choose Manage user certificates:

10. Go to Trusted Root Certification Authorities:


11. Right-click and highlight All Tasks, click Import…

12. Choose the .p12 file downloaded before:


Then Next, then Next, then Finish.

RUT configuration:

   The final part:
   Go to SystemAccess ControlWEBUI

1) Turn off Certificate files from device.


2) Click browse in Server certificate and choose the [.crt] file created.

3) Click browse in Server key and choose the [.key] file created.

4) Click SAVE & APPLY.


Open the WebUI again using the DNS record:

Now we can access the WebUI securely, and we can turn of the HTTP access.
