Failed to fetch device certificate. OTP is not valid

L3 Networker



So, Failed to fetch device certificate. OTP is not valid issue.


Secondary NTP Server :



mgmt interface mtu : 1500 (default)



I have changed the mtu value, but the same phenomenon is happening.

So you've attempted to set MTU on the management interface to 1374 and you're still running into the same issue? Also your device certificate as of your screenshots is valid and showing as renewed today, have you tried just hitting 'Get certificate' again to make sure it's not just a cosmetic issue? Certainly seems like at least at some point today you managed to grab the current certificate without any issue.
