Is anyone else having Let's Encrypt certificate errors through their Web Appliances ?? As of today we are getting a lot of sites blocked due to the X3 expiration.
DST Root CA X3 Expiration (September 2021) - Let's Encrypt (letsencrypt.org)
Seems like a fix is on the waysupport.sophos.com/.../KB-000042994
This change causes a lot of confusion, many sites stop working. This is a very undesirable action. Brother, you are not the only one affected by this.
