Código de error: 20400. Alguien ha solucionado este tipo de inconveniente

​@lu_creativa Error 20400 typically indicates that Illustrator cannot verify your Adobe account or communicate with Adobe's servers. It is usually related to connectivity, authentication, VPN, firewall, or Creative Cloud sign-in issues rather than the Illustrator file itself. 

I did check Adobe Status servers, and on Octber 14, 2026, everything seems fine on their end, https://status.adobe.com/products/503524

Have you tried since October 14th? Is it working for you now?
