408 authentication time out on new install

[E-dk]

After a new install i have the error 'Error while logging in' Authentication Time Out 408. when i connect from Moodle. I have another install thats working fine which i installed a few months ago with the same installation options. The only slightly resembling issue i could find was https://github.com/bigbluebutton/bigbluebutton/issues/9400 . Because this server also has a lot of cores (96). The fixes proposed there don't work for me. Any suggestions?

[ffdixon]

Are you able to install the API examples and launch into a meeting? We just tried using 2.2.28 (soon to be released) with Moodle and didn't get any errors on startup.

If you want to try 2.2.28 on your server, run bbb-install.sh and use the parameter -v xenial-220-dev22a.

Also, 96 cores is overkill at the moment. The nodejs process within mongodb runs on a single CPU core, so in 2.2 it constrains how many users a BigBlueButton server can support. We're working on improving this in 2.3.

Fred, thanks for your reaction. I will try 2.2.28. Actually i tried 2.3 last evening but that didn't solve the problem. Regarding to the number of cores, maybe a workaround could be to install hyper-v on this server and install BBB as one or two HV guest(s)? Or is this still not advisable because of Freeswitch requirements? I have a environment with 1500 students and 100 teachers, due to covid19 i assume at some point i might have 500 concurrent users in the near feature.

[E-dk]

Tried 2.2.28 to no avail. My gut feeling says problem is ubuntu-hardware related. New Poweredge r6525 with 2 AMD EPYC 7642 procs.

[E-dk]

Installed as a HV guest on the same server (now with windows server 2019 installed), assigned 16 cores, works instantly. Just fyi.

[ffdixon]

Thanks for sharing -- it would be better to use a number of smaller VMs (with 8 CPU cores/16G of memory) front-ended by scalelite.

[E-dk]

Thanks again for your input. I'm going to try scalelite - until i have enough knowledge i will split the population in 3 or 4 portals with corresponding bbb severs.

I had the same problem on v2.2.28 and digged into the race condition between bbb-apps-akka and redis as mentioned here https://github.com/bigbluebutton/bigbluebutton/issues/9400#issuecomment-649523930 After analyzing the systemd-startup tree using systemd-analyze plot > tree.svg I saw that bbb-apps-akka starts ~4s before redis.

For me the solution was to create an override-file for redis-server using systemctl edit redis-server.service with the content:

[Unit]
Before=bbb-apps-akka.service

Now redis starts before bbb-apps-akka, I will report new issues triggered by this solution here, but for now that works.

Edit: needed to move bbb-apps-akka in front of bbb-fsesl-akka using systemctl edit bbb-apps-akka because audio connection was not working then:

[Unit]
Before=freeswitch.service bbb-fsesl-akka.service

I face the same issue with the same situation. I'm trying @paul1278 fix and we'll let you know if it helps.

[tcg71]

Same problem here after first update on a new system created 3 weeks ago: The solution @paul1278 provided is working, but still needs a bbb-conf --restart after each system restart.

[paul1278]

@tcg71 it works without a restart here, maybe there is another race condition somewhere, you could try analyzing your startup using the command mentioned earlier: systemd-analyze plot > tree.svg and then open the tree.svg-file.

[tcg71]

@paul1278 I created the file, but I can only see that bbb_record_core.slice starts before the network is ready. But I don't see any hint of redis and akka.

tree.svg.zip

[paul1278]

@tcg71 do you start redis and akka in Docker-containers? Because then you need to put those in correct order

[crosscodr]

I also couldn't see much in my tree.svg from systemd-analyze, and found this hint from https://www.freedesktop.org/software/systemd/man/systemd-analyze.html:

Also note: systemd-analyze blame doesn't display results for services with Type=simple, because systemd considers such services to be started immediately, hence no measurement of the initialization delays can be done.

[ffdixon]

We're adding some dependencies in 2.2.30 to ensure redis starts first. Also added to bbb-install.sh if you use it now to setup BigBlueButton.

https://github.com/bigbluebutton/bbb-install/blob/master/bbb-install.sh#L363

[E-dk]

Fred i assume its still better to split the load over multiple virtual bbb servers with scalelite, than to have one large physical bbb server. I now have 8 virtual servers on 2 physical servers with scalelite in front. Works excellent.

[paul1278]

@E-dk yes it still is, my fix is not for that problem, but for the problem on starting BigBlueButton on bigger servers.

Hello to all

Is it an option for you to install the latest version of 2.4? It will be easier for us to help if you work with the current released version.

@ffdixon

Hello Dear I try to make my problem clearer For now, I want to ignore the problem I mentioned and address another issue that may be related to this one. I turned off the BigBlueButton server that and I had installed and had a problem and re-installed the latest version of BigBlueButton and Greenlight on Ubuntu version 1804 I went through all the settings and installation steps correctly and the rooms that are being built in BigBlueButton are also working properly so far. My problem starts when I create a room on my site using secret code BigBlueButton, but I can not access it. I enter the address "https://mconf.github.io/api-mate/#server=https: //server14.lmsschool.ir/bigbl "and matched the room ID made in BigBlueButton with the rooms made in the site and the IDs was the same, but it is not possible for me to enter the room through the site and With the message " FAILED <messageKey> checksumError </messageKey> Checksums do not match " thank you for your help. It should be noted that my site is working properly on another server, but I have a problem with this server Tell me if you need other information. thank you
