[CentOS] getssl was working stopped

Hi All  - I am using getssl on CentOS 7.
It have been working fine since  Feb 17th and just stopped.

My script:
getssl -u -a -q
getssl: for some reason could not reach
http://MY_NAME/.well-known/acme-challenge/lL_ublhWh3fnmbXhhh3BR3bdnjHoMFAgTimTvZUTLQM
- please check it manually

So I did check it manually from another machine - it works fine:
curl
http://MY_NAME/.well-known/acme-challenge/lL_ublhWh3fnmbXhhh3BR3bdnjHoMFAgTimTvZUTLQM

lL_ublhWh3fnmbXhhh3BR3bdnjHoMFAgTimTvZUTLQM.tIS27xF0xtz7YHES31MATofXyCeyfqttq7B_YBYZetI

So it works fine.

I then thought perhaps a firewall issue. So I "systemctl stop firewalld",
redid the getssl -u -a -q command above - and I get the same error.

How do I see/tell what its not liking ?

Thanks,

Jerry
