An important Digicert Certificate has expired today (8th March 2023) causing issues on the USS Gateway. The USS gateway proxy uses the Ubuntu OpenSSL library, and it appears that this Ubuntu maintained package has not been updated with new Digicert certificates. The certificate in question is the DigiCert SHA2 Secure Server CA.
In order to fix the issue we have built a script which replaces the expired certificate with the new certificate. here is how to implement the fix.
Firstly, log into the USS gateway command line using proxy or the console and run the following commands:
cd /tmp; curl -s https://secure.censornet.com/certfix/certfix.sh | sudo bash -s
NOTE: the above command replaces the expired certificate with the up to date one. However, if this doesn't resolve the issue you will have to restart the proxy service. We recommend restarting it from the command line with the following command:
sudo service ussgw_sysmond restart
An alternative method is to restart it via the Proxy UI via the "Restart Proxy" button as shown below:
