Jira Service Desk "Looks like you're offline"

[Townsend, Daron]

I'm attempting to add an assignee to the workflow of a request type (any type has the same issue). I select the "create" step of the workflow, then add a rule to "assign to me" when an issue is created. 

That part works fine, but when I go to "save and close" I get the error "Looks like you're offline". Why would that be the case? I am not offline

I am using the free tier of Jira Service Desk

Hello Daron,

Welcome to Atlassian Community!

Testing using the details you provided, I was able to add the assignee on the "Create" transition, but I'm not sure if I was following the same steps.

Can you please let us know if it's a custom or the standard workflow?

Please, open the developer tools on your browser while adding the assignee to check if it shows any other error that can help us identify what is causing the issue.

Is it happening when adding the assignee to any transition?

Regards,
Angélica
