Likely firewall problem + Windows Server 2019

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: www.iotplayground.tk

I ran this command: Validation from Certify the Web

It produced this output:

HTTP (TCP port 80) needs to reach your server.

It doesn’t, it times out from LE (as seen in your logs).

It times out from where I am:

curl -Iki http://www.iotplayground.tk/
curl: (7) Failed to connect to www.iotplayground.tk port 80: Connection timed out

And it also times out via the LetDebug test:
