 On September 30, 2021, a digital certificate used by Let's Encrypt expired, making Internet connections impossible for many devices. To fix this, we need a new certificate. To get the new one, do one of the following. Number 1. Double check that you have the latest update on your device or computer. Number 2. Use the Firefox browser. This is only for connecting to the Internet. Firefox uses its own certificates. Number 3. If possible, upgrade to the latest operating system on your computer. Number 4. Install the certificate manually on your computer or mobile device. For Android devices, go to the link that is in the description below. Once the file has been downloaded, run it. Keep in mind you must name the certificate ISRG root X1. Now, enable a pin or pattern. You will receive a confirmation once the certificate has been installed. You can assure the certificate is installed correctly by going to settings, security, trusted credentials, and finally, user. For Windows 8.1 and Windows 10, go to the link that is in the description below. Go to the download folder or wherever you have downloaded the file. Double click on it. Now, click on open and then click on install certificate. Here select the local machine, click on next, and finally on finish. For Mac computers, go to the link in the description below. Go to the download folder and double click on the file. The system will ask you for your password. Type it and click on modify keychain. The keychain access window will open showing you the certificate has been installed. However, a red X will let you know that you should accept the new certificate as trusted file. Double click on the SRG root X1 certificate. A new window will open with detailed instructions. Click trust to expand these options. Here, change when using the certificate to always trust. This option will automatically change all values to always trust. Close the ISRG root X1 window. Again, the system will ask you for your password to confirm the process. Type it and click on update settings. Now on the keychain access window, you will see the certificate with a blue plus icon to let you know the certificate is trusted for all users. Congratulations! The certificate has been successfully installed. The following is a list of devices that have this problem. Burn to Learn is working to help you understand the changes in technology as they happen.
