[BlueOnyx:25120] Let's Encrypt problem, 5208R

[Darren Shea]

I can't seem to get the 5208R system to properly execute the Let's Encrypt
process - it seems to create the token, but complains of "Verify
error:Invalid response from
http://<domain>/.well-known/acme-challenge/tokenname [public IP]:" then it
tells me to check a non-existent file in a non-existent directory:
/var/log/letsencrypt/letsencrypt.log

Is there a fix for this short of migrating to a later version of Blue Onyx?
