Unable to access NMC3 via HTTPS using Chrome - ERR_CERT_INVALID

Problem:
Users are unable to access an NMC3 with a self-signed certificate via HTTPS using recent versions of the Google Chrome browser

Environment:
UPS Network Management Card 3 - AP9640/41/43
Devices that use an embedded NMC3, including but not limited to PDU (2022+ model AP8xxx, APDU9xxx), ATS (AP44xxA), and Smart-UPS/Symmetra UPS systems

Cause:
A recent Chrome update is blocking the self-signed certificate ECC certificate that is used by default on an NMC3.

Resolution:
This will be addressed in a future version of firmware, and this article will be updated when a fix version is available.

Please note that this issue is fixed from firmware rev. 2.4, so updating firmware should be fist step in the troubleshooting process.

Secondary workarounds are:

• Use a different browser
• Use an older version of Chrome
• Delete the ECC self-signed certificate on the NMC and generate an RSA cert. The commands can be performed via the CLI:
  • apc>ssl key -d
  • apc>ssl key -rsa [1024|2048|4096]
• Use the CLI Security Wizard and a 3rd party certificate authority to create a signed certificate
