Hi @Hamed.khosravi


Thanks for posting the question on the AppDynamics Community.


At first glance, we have the following recommendations:


1. Refer to System Requirements and see you have the correct versions of components installed and have met the network requirements.

2. Check the SSL connection.


If you have more details on the setup, kindly share with us. We will have someone on the moderator team specialized in Database Monitoring to look at your issue.


Thank you


Hi @Radhika.Puthiyetath


I solved the problem a few days after it came out, I tried various ways to complete configuration of the Events service step but the problem was related to the version of the operating system. I used Centos7.5 for my Environment for deployment but it doesn't work properly, some day I decided to change it to CentOS6.10 then it's working now.


Thank you.
