If i test same from my local system..it is working fine.
We are not able to find exact issue, why it is not working from some systems (blocking flex api url)
Could you please help us to sort out this issue.

Hello, Vasu, 
 
Thank you for your reply.
 
It seems there might be some sort of misunderstanding so let’s clarify some points.
 
As described in your initial question, you are using Flexmonster Data Server and for some systems a 500 error occurs while trying to access the Flexmonster Data Server API.
However, the configuration that you provided is for Flexmonster Accelerator, not for Flexmonster Data Server.
 
Could you please confirm that you are using Flexmonster Data Server?
 
If you are using both Flexmonster Accelerator and Flexmonster Data Server, could you please let us know if the 500 error occurs for Flexmonster Data Server or for Flexmonster Accelerator? Since the Flexmonster Accelerator and Flexmonster Data Server are separate tools designed for different cases, the reasons for the error could differ depending on the used tool. 
 
Waiting for your response.
 
Kind regards, 
Vera

Hello, Vasu, 
 
Thank you for confirming that you are using Flexmonster Accelerator. 
 
Our team kindly suggests the following: 

  1. Opening the port in the firewall:
    To allow connections to the Accelerator from outside the server, the port needs to be opened in the firewall. 
    Please make sure that the port you specified in the configuration file (443) is opened in the firewall.
  2. Checking if the server certificate was registered successfully:
    Could you please confirm if the server certificate was registered successfully as described in the following guide: https://www.flexmonster.com/doc/configuring-secure-https-connection/?
  3. Also, could you please check if the issue persists when HTTPS is disabled?
    It is possible that the API is blocked due to a certificate validation issue. 
  4. Specifying the ALLOW_ORIGIN property:
    There is a possibility that defining specific origins could help to resolve the issue.
    Several origins can be defined as follows:
    ALLOW_ORIGIN = http://localhost, https://example.com
  5. Also, could you please provide the Accelerator logs where the 500 error occurred? 
    The logs can be accessed by clicking the "Logs" button in the Flexmonster Accelerator Manager.

 
Please let us know if this helps.
Looking forward to your response. 
 
Kind regards, 
Vera
