[users at bb.net] All slaves shown as 'offline' but both master and slave twisted.log show connection

[Caleb Crome]

Hi all,
   I'm bringing up a new buildbot master with a previously working master.cfg.

I'm running both master and slave inside the same docker, so my first
thought is some port mapping issue, but not sure.  All seems to be
correct.

buildbot version 0.8.12
ubuntu linux.


after buildbot start master:
------ master/twisted.log -----
... all seems okay ...
PBServerFactory starting on 9989
... all seems okay...
2017-04-10 18:33:50+0000 [-] BuildMaster is running


Then i create a slave:
buildslave create-slave slave-64-bit-linux localhost:9989
slave-64-bit-linux password
----- slave-64-bit-linux/master.cfg -----
2017-04-10 18:35:02+0000 [-] Loaded.

2017-04-10 18:35:02+0000 [Broker,client] sending application-level

And back in master/twisted.log I get:
2017-04-10 18:44:18+0000 [Broker,2,172.17.0.1] slave
'slave-64-bit-linux' attaching from IPv4Address(TCP, '172.17.0.1',

keepalive timer for 'slave-64-bit-linux'
2017-04-10 18:44:18+0000 [Broker,2,172.17.0.1] bot attached

which sure seems fine to me.

However when I take a look at my web server, it shows the slave is offline.

I did in fact verify that when I stop the master, the buildbot website
stops working (just making sure that there are not 2 buildbot masters
running).

Any ideas?
Thanks,
