Hello,
Thank you for bringing this up. This seems to be recurring issue. I would like to have more details to replicate it and forward to the development team.
Could you provide the firmware you had before update?
How did you update the device:
- Via WebUI or RMS
- With Keep settings set to on or off?
How were the certificates generated?
Could you replicate the issue, then access router's WebUI, go to System -> Administration -> Troubleshoot section and download troubleshoot file. Attach this file by editing your question or send it to me in a private message.
Best regards,
