Welcome to the Atlassian Community!

This is something you need to report to your Jira admins, as they should have access to the application logs (and they're the ones who you will need to talk to about raising support requests with Atlassian - you'll need some information they have, but it's better that they do it, there's a "raise support request" built into Jira and it's quicker and easier if they use it)
