Invitation problems

Klastro sends two kinds of invitation by email:

• an account invitation, to join Klastro or an organization (Join your team on Klastro, Your invitation to Klastro);
• an assessment invitation, to take a technical assessment as a candidate.

Each problem below is laid out as Symptom, Cause and Fix. For the normal flow, see Accept an invitation.

Account invitations

“This invitation has expired”

Symptom. The link opens a page titled This invitation has expired.

Cause. Invitation links stop working after a few days.

Fix. Ask the person who invited you for a new one. An organization admin can send it again from the team page with Resend invitation; the new email contains a working link.

“This invitation was already used”

Symptom. The page shows This invitation was already used (“The account for this invitation is already set up.”), or This link was already used.

Cause. Each link works once. Your account already exists, or you opened the link before and did not finish choosing a password.

Fix. Select Sign in and use your account. If you never finished setting your password, open app.klastro.io/auth/recovery and follow the recovery steps. You can also ask your organization admin to resend the invitation.

“This invitation was withdrawn”

Symptom. The page shows This invitation was withdrawn.

Cause. The person who invited you cancelled it.

Fix. Contact them if you think this is a mistake. Only they can send you a new invitation.

“A newer invitation was sent”

Symptom. The page shows A newer invitation was sent.

Cause. You were invited again, which replaced the earlier link.

Fix. Find the most recent invitation email and use its link.

“This link does not work”

Symptom. The page shows This link does not work (“The invitation link is incomplete or not valid.”).

Cause. The link was cut when it was copied, for example across two lines, or it was modified.

Fix. Open the link directly from the email instead of copying it. If that fails, ask for a new invitation.

“We could not check this invitation”

Symptom. We could not check this invitation. Check your connection and try again., or We could not start account setup. Try again in a moment.

Cause. A network problem or a temporary service issue.

Fix. Check your connection and select Try again.

Assessment invitations (candidates)

“Invitation Expired”

Symptom. The invitation shows Invitation Expired, or the list shows This invitation has expired. Contact the organization for a new one.

Cause. The recruiter set an expiry date and it has passed. The invitation’s Expires On date shows when.

Fix. Contact the recruiter or organization that invited you and ask for a new invitation. Klastro cannot extend it for you. When an invitation shows Expiring Soon, start the assessment before that date.

“Invitation Revoked”

Symptom. The invitation shows Invitation Revoked (“This invitation has been revoked by the organization.”).

Cause. The organization cancelled it.

Fix. Contact the organization if you think this is a mistake.

“Unable to load invitation”

Symptom. Unable to load invitation: “This invitation may have been revoked, expired, or is for a different email address.”

Cause. You are signed in with a different email address from the one the invitation was sent to, or the invitation is no longer valid.

Fix. Sign out and sign in with the address that received the invitation email. Also check that the right organization is selected; see Sign-in and organizations.

I can’t start the assessment

What you see	Cause	Fix
Accept Invitation First	You have not accepted the invitation yet.	Go back to Your Invitations and select Accept.
Too many sessions are running right now. Please try again in a few minutes.	The platform or the organization is at capacity.	Wait a few minutes and select Start Assessment again. Your invitation is not affected.
Failed to start assessment	A temporary problem.	Try again. If it persists, report it with the category Assessment.
Assessment Completed	You already finished this assessment.	Nothing to do: the recruiter receives your results.

If the assessment needs a recruiter’s approval before it starts, the lab shows Waiting for your session to be authorized… until they approve it. See Lab preparation.

For recruiters and admins

Situation	Fix
A candidate’s invitation expired.	Send a new invitation from Invitations. See Send invitations.
Already invited: “A pending invitation exists for this email. Revoke it first.”	Open the existing invitation, select Revoke, then invite again. Or select Resend email to send the same invitation again.
A member’s invitation shows Link expired on the team page.	Select Resend invitation: the new email revives it.
A member’s invitation shows Setup started.	They opened the link but did not choose a password. Ask them to open app.klastro.io/auth/recovery to recover their account, or resend the invitation.
