Stop it: "Let's Encrypt certificate renewal failed!"

[shoulders]

Just a thought:

Try setting a self-signed certificate and then disable the server, give it 5 minutes for any cron jobs to run and then re-enable the virtual server.

Are these links any good

• Let's Encrypt trying to renew deleted domains · Issue #185 · virtualmin/virtualmin-gpl · GitHub
  • Deleted virtual host still in LE renewal logs
  • LE (still) not renewing automatically in Webmin
• Let's Encrypt automatic renewal: Uses shared certificate instead · Issue #674 · virtualmin/virtualmin-gpl · GitHub
  Looks like it’s possible for LE auto-renew to still happen when the cert is shared with another domain … I’ll fix that.
