here is the log
- The following errors were reported by the server:
Detail: Failed to connect to 18.104.22.168:443 for TLS-SNI-01
To fix these errors, please make sure that your domain name was
entered correctly and the DNS A record(s) for that domain
contain(s) the right IP address. Additionally, please check that
your computer has a publicly routable IP address and that no
firewalls are preventing the server from communicating with the
client. If you’re using the webroot plugin, you should also verify
that you are serving files from the webroot path you provided.
and this shows the correct ip address
$ nslookup www.swigger.net 22.214.171.124
le uses a very old ip address 126.96.36.199 which I changed at lease one month ago.
Please help to correct that.
