How to register Buildbot worker with master?

I had to replace a Buildbot master server, and even though I seemingly reinstalled it with the identical code and settings as before, I must have missed something, because it's now rejecting all requests from all existing workers with errors in its twistd.log file like:

2018-08-22 21:17:28-0400 [Broker,678,10.229.39.202] invalid login from unknown user 'worker2'
2018-08-22 21:17:28-0400 [Broker,678,10.229.39.202] Peer will receive following PB traceback:
2018-08-22 21:17:28-0400 [Broker,678,10.229.39.202] Unhandled Error
    Traceback (most recent call last):
    Failure: twisted.cred.error.UnauthorizedLogin:

How do I re-register the workers with master? The docs don't mention this, nor where the worker username/passwords are stored. I tried re-running the buildbot-worker create-worker ... commands and then restarting Buildbot, but that had no effect.

Goog day. In a worker name/pass stored in a buildbot.tac

Name/pass in a worker must be same as in master.cfg file at master.

For example, if master.cfg on master contain

 c['workers'].append(worker.Worker('remote-worker', 'pass'))

a buildbot.tac at worker should contain

...
workername='remote-worker'
passwd='pass'
...

Please, note, that if you make a changes in a master.cfg you should upgrade master via command buildbot upgrade-master: http://docs.buildbot.net/current/manual/installation/buildmaster.html

The upgrade-master command is idempotent. It is safe to run it multiple times. After each upgrade of the buildbot code, you should use upgrade-master on all your buildmasters.

P.S. On 3rd September buildbot team presented new version 1.4 I have buildbot master 1.3 and one buildbot worker 1.4 and it work correctly
