I am connected to the DevNet Sandbox VPN and can reach the APIC at 10.10.20.14.
Direct HTTPS access was successfully tested using:
curl.exe -vk https://10.10.20.14
The APIC responds successfully with:
HTTP/1.1 200 OK
Server: Cisco APIC
I also tested:
curl.exe -vk https://10.10.20.14/api/aaaLogin.json
The APIC responds with:
HTTP/1.1 400 Bad Request
Failed to parse login request
This is expected since the request was sent as GET without login credentials.
Therefore, VPN connectivity, routing, TCP/443 and the APIC HTTPS service are working. The issue appears to be specifically related to the SSL certificate trust/validation.
The browser still reports:
we could not verify the certificate: reason = untrusted
I also exported and installed the certificate locally, but the issue persists.
Sandbox reservation:
ACI Simulator 6.0-20260831T21151927
Could you please check the APIC certificate on the Sandbox side?
