Website reset password with this error

I used my other account for long time, but I forgot the password. I reset the password, and received the reset password link. but when I click the link, the community forum shows error:

The reset password token you have provided has timed out.

I have tried few times, all the results are same. I think the forum has some problems, the problem looks this:
please help to check the reset problem. I want to use the previous account in future.

Was your previous account from when this was a completely separate forum? If so as part of the migration it was cloned into the current system, but is inactive as passwords and other data could not be copied.

somehow, It works again, I can reset the password now. thanks!
