hi! I have licensed applications Jira Service Desk and Jira Software. Jira Software app works well. But I can't create any Service Desk project!

I select any type of Service Desk project and click on the Next button.

Then I enter the project name, key, Project Lead in the fields and click on Submit button. Аn error appears on the screen: "Hmm... we couldn't create your project due to an unknown error. Try refreshing the page to start again." Refreshing the page or anything else does not work.

Other JIRA projects are added and working properly.
