I have a dev setup of openstack ansible AIO with heat installed

heat is giving me an internal server error which i have pasted it in the link below because it is too big can someone take a look at it ? thanks is the public IP of this server running openstack

this is the log from heat.log when i actually enter heat commands such as openstack stack list

here is the grep output for from heat.conf

does this make sense ?

This is debug output from the openstack client. The openstack client sees that there is something wrong with Heat, but it can't look inside Heat. To understand what is wrong, you have to look at Heat's logs. Usually, they are found at /var/log/heat, but this may be different in OpenStack Ansible.

Well, there is an interesting bit of information, namely that the connection to fails since the TLS certificate can't be verified. Where does this address come from? Further up in the output, is used.

I would grep this address in the Heat configuration.

The log doesn’t show the messages at the time the error occurs. But I am convinced that the problem is the invalid certificate at Either correct/renew the certificate, or don’t use https in the config file.

TLS configuration is documented at, though this is for Pike. I didn’t find the equivalent page for Rocky.

Also, since you have a private IP, why don’t you use it for communication internal to the cloud?

I do not use SSL certs . this server is going to be behind a vpn soon so no worries there

i solved the problem with heat . I replaced the public ip in heat conf with the private 172.xxxxx which is the ip for br-mgmt interface , restarted the heat container and the problem went away

actual heat commands like openstack stack list now show nothing and this is normal

i did not actually enter the public IP in the heat conf , it was entered by the openstack ansible role so i guess i must find a way to tell it not to use the public ip if this is possible
