Either firewall rule was not added for Nginx port ‘8092’ or rule was not permanently added on Backup server
This error message is not correct , I have run the below command and i did the checks. I dont know what i have missed as its working in validation.
firewall-cmd --zone=public --permanent --add-port=8092/tcp
firewall-cmd --zone=public --permanent --remove-port=5004/tcp
Note: Before I have tested the port from jump server and it was not working. after relaod its started working. Always high value experience tasks are getting failed without any reasons and its creating unnecessary stress also.
