If you are using eazyBI on the Jira Server/Data Center, could it be that outgoing network connections are disabled for your Jira server?
If network connections are allowed, please send eazyBI log files (Troubleshooting) to our support email support@eazybi.com.
Thank you for confirming that the network restrictions were the reason for the error.
Regards,
Jānis
P.S. We have a separate app for monday.com data analysis - https://monday.com/marketplace/10000162.
Also, I added your reference to an internal improvement request to enable monday.com data import into eazyBI for Jira Data Center.
