Why can't users accept my invite to join Jira Software?

[Svoren_ Yaroslav]

Hello! I am trying to create a planning for a small team that I'm in, so decided to use free version of Jira.

As I understand, I may have up to 10 users, which is plenty for me.

Before sending the invites out, I have invited my personal email to make sure everything works, and sadly when I try to accept the invite (from incognito mode, from another browser, from phone) I see the redirecting between 3 pages, followed by a screen from Atlassian saying "You're almost there. It looks like our database is taking a little longer than usual to sync up. Wait a few moments then try again.". 

My private email was previously registered with Atlassian, so I even opted to invite yet another email that never used Atlassian products before, same issue.

I can see my both invited users in "User management" tab.

None of them are visible in "Project settings --> Access".

As I'm using the free version, they should already have access to my project, but they don't.

I have tried logging to Atlassian website with those profiles, and for both of them the project is visible, but when trying to open them, the same redirecting 3 pages followed shortly by the same error occurs.

What can I do to invite users to my Jira Software project?

Ok, so I've tried using my old private gmail account as a host of website and consequently project.

For some reason the inviting worked out from it.

I do not know why using my organization's work email as a host lead to invited users not being able to accept invites.

Ok, one short celebration later I tried joining the original project with organization's work email as host, and now it works.

Whoever did this, thanks!
