What the error means
The ticket no longer accepts replies, either because it was closed or because your account is not permitted to reply.
Why this happens
The ticket was marked resolved and closed. The ticket belongs to another account. Your session expired, so the reply was rejected.
How to fix it yourself
- Sign in to your account first.
- Open the ticket from your account, not the email link.
- If the ticket is closed, look for a Reopen option.
- If you cannot reopen, open a new ticket and reference the old number.
When to contact support
If replies are blocked for no reason, contact support and include both ticket numbers.
