Getting 500 error "Backend Error" immediately after install for all projects

Have contacted support via the link inside the error but haven't heard a response in nearly a week.

When accessing the Gannt Cloud plugin from any of our Jira projects:

Backend Error
An unknown error occured while contacting with Add-on's backend: 500 Internal Server Error
The problem might be temporary so you can try to reload this page later. Report a problem

Hey Mick,

I feel this is something only the plugin developer can help you with considering it is an OnDemand plugin. Recommend raising another issue in the issue tracker link provided in the below page.

Hi Bhushan,

Thanks for the suggestion, have emailed them directly from the link you provided. The "Report a problem" link opened up a generic web form so I'm concerned the initial report didn't make it to them.

Hi Michael,

Thank you for the feedback. I will contact you directly in order to resolve this issue.

I am having a similar issue. Please let me know if you were able to resolve your issue


There was a problem affecting the instances with the high number of projects/issues and, I believe, has already been resolved a while ago. Let me know if that's the case. Thanks!
