Workspaces are only accessible by certain specific IP addresses. When you first created your workspace, this is the IP address that was recorded. If you try to access your workspace with a different IP address (for example, if you created the workspace at home, then went to a coffee shop), you will need to update the IP addresses that are allowed to connect to your workspace. We can do this by updating the “CIDR block” section of the workspace configurations.

Click “Edit CIDRs”

Click “Add My IP” for each section and then click “Submit”.&#x20;

{% hint style="info" %}
GIC BCH users: Do not click "Add My IP" instead, type the same IP address into the box, changing the last two digits from "/32"  to "/24" and click submit.&#x20;
{% endhint %}

You can add a maximum of 5 IP addresses to this section. If necessary, remove older IP addresses.&#x20;

You may need to stop & restart your workspace, refresh the page, and wait a couple of minutes for the changes to take effect.&#x20;

If clicking "Add My IP" doesn't appear to resolve the problem, verify that the IP address being added matches your current IP address. You can do this by going to a website such as <https://whatismyipaddress.com/> and checking the IPv4 address to see if it matches.\
\
Also, make sure your Workspace is set to "Available". You can not remote access without the Workspace being available.&#x20;
