LUA record - ifurlextup() not working

[huntx]

I am trying to create a LUA record using the ifurlextup function.
There is a HTTP application running on the same server as PowerDNS, hosting the URL - https://127.0.0.1:5000/check/<probe_ip>/ which will return HTTP code 200 if the probe IP is ICMP reachable, else HTTP code 404.

The LUA records is created as below:
lua.records LUA A "ifurlextup({{['192.168.1.1']='https://127.0.0.1:5000/check/192.168.1.1/',['192.168.2.2']='https://127.0.0.1:5000/check/192.168.2.2/'}})"

But, I am seeing the errors:

pdns_server[303793]: LUA record monitoring declaring [externally checked IP] DOWN for URL https://127.0.0.1:5000/check/192.168.1.1/, error: Unable to retrieve URL (0): Couldn't connect to server
pdns_server[303793]: LUA record monitoring declaring [externally checked IP] DOWN for URL https://127.0.0.1:5000/check/192.168.2.2/, error: Unable to retrieve URL (0): Couldn't connect to server

I can confirm the HTTP application is working, as I am able to curl the URL and got the intended response.

python3[298066]: 127.0.0.1 - - [06/May/2024 14:58:12] "GET /check/192.168.1.1/ HTTP/1.1" 200 -
python3[298066]: 127.0.0.1 - - [06/May/2024 15:07:54] "GET /check/192.168.1.2/ HTTP/1.1" 200 -

But, none of the pdns healtcheck request is observed on the HTTP application.

How can I troubleshoot further ?

It was due to SELinux blocking. Case closed.
