In our 2024.R1.0 release we introduced an additional layer of security, meaning an OTP code is mandatory to use the Admin account. (for ConfigHub and TrendHub login)
You can read more about this in the article from Jef Vanlaer here.

While trying to authenticate with the Admin account, I ran into following error message:  Invalid authenticator code

I found out that the root cause of this error is due to my TrendMiner server time not being in sync, thus the server thinks that the code I am providing is long expired/not valid yet.

After resolving the NTP issue my Admin login is working without issue again.
