@rash419 that worked, thank you.
For anyone else’s reference, this is what I did.
Logged into the container as root, installed nano and then edited /etc/coolwsd/coolwsd.xml
sudo docker exec -u 0 -it “container_ID” /bin/bash
apt update
apt install nano
nano /etc/coolwsd/coolwsd.xml
Changed mode from “first” to “groups”
<alias_groups desc="default mode is 'first' it allows only the first host when groups are not defined. set mode to 'groups' and define group to allow multiple host and its aliases" mode="groups">
Added the following lines below that:
<group>
<host desc="hostname to allow or deny." allow="true">https://domain1.com:443</host>
</group>
<group>
<host desc="hostname to allow or deny." allow="true">https://domain2.com:443</host>
</group>
<group>
<host desc="hostname to allow or deny." allow="true">https://domain3.com:443</host>
</group>
You can obviously have http:// and port 80, if you that is allowed in your environment.
