My domain is: timder.app
I ran this command: sudo certbot certonly --standalone -d timder.app -d www.timder.app
It produced this output: Certbot failed to authenticate some domains (authenticator: standalone). The Certificate Authority reported these problems:
Detail: 126.96.36.199: Fetching http://timder.app/.well-known/acme-challenge/Lt4f61zD3aYEwtw3BJyrBXsip71XcW-vmWKpEM6nL5M: Timeout during connect (likely firewall problem)
Detail: 188.8.131.52: Fetching http://www.timder.app/.well-known/acme-challenge/-jtSAeDlDmJlXXNqOzLGCPipE4GzgSOaHUKucKiJbxY: Timeout during connect (likely firewall problem)
Hint: The Certificate Authority failed to download the challenge files from the temporary standalone webserver started by Certbot on port 80. Ensure that the listed domains point to this machine and that it can accept inbound connections from the internet.
The IP is the address of the old instance that I terminated.
What can I do?
