Unable to get into Confluence and cannot reset password due to

[Katherine Riverwood]

Specific login error is:
"The following error(s) occurred:

• Please re-enter your login details and type in the word below."

I have entered all my usual passwords multiple times and I am surely getting the capture word correct.

Reset error:
"Sorry, you can't retrieve your password as no email service has been configured for Confluence. Please contact your administrators for assistance."

Is my account locked and it's not telling me? I don't understand how NO passwords can be working.
What can I do to regain access please? I am the admin.

It is likely that the user directory system has failed.  You should be able to tell from the logs what is wrong (even if it's not that) - see <confluence home>/log/atlassian-confluence.log

If the user directory is ok and you are locked out, then see https://confluence.atlassian.com/doc/restore-passwords-to-recover-admin-user-rights-158390.html
