Hello

I am a bit confused. I use ACME with dynu DNS challenge and when ordering new certificate via WebGUI all works fine.
However the command line from crontab

"/root/.acme.sh"/acme.sh --cron --home "/root/.acme.sh

fails as:

[Fri 16 Jul 2021 11:54:31 AM PDT] Getting Dynu token.
[Fri 16 Jul 2021 11:54:32 AM PDT] Authentication failed.
[Fri 16 Jul 2021 11:54:32 AM PDT] Can not get token.

Why?

Thx
