I've got problem with REST API. I've noticed LMT tema.log shows:

0000047f com.ibm.ws.webcontainer.webapp I SRVE0292I: Servlet Message - [tema]:.[WARN] An error occurred while sending a request to BigFix server localhost : An error occurred while connecting to BigFix server localhost. Ensure the server is running or associate data source with another BigFix server.. Before you can configure VM managers, you must install and run the BigFix services, including Web Reports. For more information, see the product documentation.

So I've enabled the WebReport log in order to get more details using below procedure:

https://help.hcltechsw.com/bigfix/9.5/platform/Platform/Web_Reports/c_logging_web_reports.html

..and found:

183211776 -- Connection error while updating AGGREGATEDBY: 23BIO_read_filenameFailed

How to fix it?

Please check on the WebReports configuration settings. You will see following :

setting: "_WebReports_HTTPServer_SSLCertificateFilePath"

value: "cert.pem"

So it seems that the setting's value does not specify the path. For example, in my environment I use default certificate and I have:

setting: "_WebReports_HTTPServer_SSLCertificateFilePath"

value = /var/opt/BESWebReportsServer/BESReportsData/SelfWRCertificate.pem

Please follow the steps in order to fixe the issue:

1. stop Bigfix services (RootServer, Client and WebReport)

2. check for the default web reports certificate location ( if you have a customer one, try first everything works with the default one ):

/var/opt/BESWebReportsServer/BESReportsData/SelfWRCertificate.pem

3. enable the web reports tracing if disabled: https://support.hcltechsw.com/csm?id=kb_article&sysparm_article=KB0023236

4. rename the actual web reports log file if it exists

5. modify the configuration file setting the correct value for the SSLCertificateFilePath setting

[Software\BigFix\EnterpriseClient\Settings\Client\_WebReports_HTTPServer_SSLCertificateFilePath]

value = /var/opt/BESWebReportsServer/BESReportsData/SelfWRCertificate.pem

6. start all Bigfix services

7. login to Web Reports, delete the previous datasource and re-create it, accepting the certificate

8. double check the AGGREGATEDBY table have been populated

Just in case you need to use a custom certificate and something goes wrong just with the custom certificate, here is the documentation you need to refer to in order to fix the issue with the custom certificate:
