Resolve the Problem by Creating a New Zone
You can resolve this issue by creating a new zone, adding the http service to it, and designating 10.0.1.11 as a source for the zone. Use these commands:
[root@$host ~]# firewall-cmd --permanent --new-zone=api [root@$host ~]# firewall-cmd --reload [root@$host ~]# firewall-cmd --permanent --zone=api --add-service=http [root@$host ~]# firewall-cmd --permanent --zone=api --add-source=10.0.1.11 [root@$host ~]# firewall-cmd --reload
Verify That the Problem Is Resolved
curl -I 10.0.1.10
