Try running this in the terminal:
For the official tutorial from remote3.it see the bottom of this post!
Check the OS Version
First, you will need to determine which version of the OS is installed on your Pi.
You should see this line:
This shows you are using raspberry pi Jessie! Or stretch will work also!
If you are using the Wheezy version of Raspbian, or to support other ARM boards using Debian (such as BeagleBone Black and Wandboard), please follow the installation directions here.
Install the weavedconnectd package
First, get the latest repositories:
sudo apt-get update
Next, download the remot3.it weavedconnectd package:
sudo apt-get install weavedconnectd
Run weavedinstaller to configure remot3.it service attachments
You should then see a list of options, press 2, then press enter
Then follow the on-screen instructions to enter your e-mail. Remote3.it will send you an e-mail with a verification code that you must enter by selecting 3 from this menu. After that, your account is active and you can add devices and services. In this case, website!
Now that you have created an account, select option 1, then log in. Note that the password is not displayed as you type.
Next, as there are no services yet installed, you will be asked to enter the Device Name. Valid characters include numbers, letters, space, underscore, and dash.
After you have entered your name, Press 1 to attach remot3.it to one of your services.
Select the type of service you are connecting to, in this case a web server so press 2 then hit enter!
You will then be asked if the default port 80 is the port to use press y, if you aren't on port 80 then put n, and then the correct port!
You can repeat this with as many ports as needed!
Select a name for the service, for example Pi-Web
After you enter the name, a few more seconds passes while it is registered to your account. Next, you will be returned to the Installed remot3.it Services menu. Now your attachment to the web service is shown. Press 4 to exit or register a new service or port with the corresponding Keys! Navigate to https://remote3.it and sign in!
You will see your devices there and can go to the link provided in your remote3.it account to access server! This link changes regularly! You don't need to port forward your router though!
