Let’s Encrypt Root CA Certificate Expires | Fortinet, Cisco Umbrella, Shopify and Dozens of Other Users Suffer Outages

On Thursday, around 10 a.m. (EST), the certificate issued by Let’s Encrypt expired and the network was covered in news reports from numerous jobs and websites around the world.

Guard Scott Helme warned Let’s Encrypt Ident Trust DST Root CA X3 expire. He predicted that the expiration would occur on September 30, and once the machines, website owners, and computers are ready, they will no longer be able to verify the certificate issued by the Certificate Center (CA).

Despite the warning, Helme scans data from Insta Page, Notify, Ledger, Cisco Umbrella, QuickBooks, Shopify, Fortinet, Google Cloud Monitoring, Azure Application Gateway, Xerox, Rocket League, OVH, PF Sense, Monday.com, Palo Alto, Heroku, Auth0, Cloud flare, and Bluecoat pages.

The business works well for most users on September 30th and writes it down. As a result, devices such as integrated systems (which are not automatically updated) as well as mobile and legacy information systems are compromised. There are likely to be issues with devices running macOS 2016, Windows XP (Service Pack 3), older PlayStations, and Open SSL 1.0.2 or initially.

A Windows IIS user reported the issue on our Encrypt website. Its configurations are as follows: (my note) -> (Suspended R3 ISRG Root X1 in 2025) -> (ISRG Root X1 removed in 2035). However, many of its users have failed with SSL (especially on the iPhone). He found an SSL administrator to check the SSL status: (My User’s Guide) -> (DST Root CA X3 3 expired open) -> (R3 DST Root CA X3 3 has expired) hours ago).

If you see this, we recommend a quick fix.

• Remove old IIS cells that have been accidentally removed from the chain.

• Remove Central Cert Auth.

• Restart the server (it is not recommended to restart the ISS)

• When using a CDN, export SSL and install.

Sean Nikkel told ZDNet: “Some users have advertised the station to allow reliable data.” Follow the instructions published in their newspaper in May. “
