can't start bbb server

[Jefatura Estudios FP]

Hello :-)

My bbb server has been working fine for a month and since this morning I get a 404 error page when trying to access the login page. It is a virtual server with no other aplication installed, just a clean installation following the instructions for installing on ubuntu

http://code.google.com/p/bigbluebutton/wiki/InstallationUbuntu

After restarting the server I get an error message:

Waiting for BigBlueButton to finish starting up (this may take a minute): Startup unsuccessful: could not connect to http://xxx.xxx.xxx.xxx/bigbluebutton/api

The command *sudo bbb-conf -c* shows

Hello Jefatura,

Are you connecting through domain name or IP i.e is your IPxxx an ip address? does it correspond to the ip address in your ifconfig. Since you say you are running on VM, i assume you used bridged mode which by default will run on DHCP, so if the address leased to the VM expires there is a chance that the new one could change, so could you confirm that? If you checked/correct all these and still have problem then you may need to provdide the output of the following:   ifconfig , cat /etc/hosts and bbb-conf --check (please indicate the ip or domain) you could use a different one for privacy if necessary.

Regards

Hi Seun :-)

Thanks for your interest. I'm connecting through an IP address (the
BBB server is integrated with Moodle so we don`t need a domain name).
I don't think it is a problem with the IP address, in fact we can
access to the default BBB page typing the server IP, it is just that
the server doesn't start, as I told before it has been working fine
more than a month... and also the IP is static, we have rented the
virtual server.

This mornig when we detect the server was down, the first thing we did
was a clean restart, so we don't have the previous logs, but we have
found some errors, I don't know if it is relevant...

as I told before it has been working fine more than a month... and also the IP is static, we have rented the

virtual server. Could you also confirm from the virtual server service provider whether they have no recent firewall rule that may be blocking? are you able to ping the ip of the BBB from your network? and could you confirm you can ping say 4.2.2.1 from within the server?

0.0.0.0  Mask:255.255.255.255                       The subnet mask does not seem appropriate to me?

Hi Seun :-)

I think you were right :-D.

After a lot of useless things I've tried, I've changed the ip address
(did I? because I got the same IP address)

sudo /etc/init.d/networking restart

And then I set the same address I had

sudo bbb-conf --setip xxx.xxx.xxx.xxx

I don't understand what have happend, but the bbb-server is now up and
running again...

Thanks for your patience with this absolute begginer...
