I mean, that would fix the issue, but that seems to be the cron job to renew SSL certs. I don’t think that will work long term as the certificates won’t renew any longer without the cron job. Right?
I would suggest enabling logging in the account.conf file, and also redirecting that cron output to a log file as well, perhaps /root/.acme.sh/acmecron.log as opposed to /dev/null to help isolate the problem.
