problem joining from lobby

[Les Piech]

we've had a couple of instances where a participant is waiting in the lobby and then is approved to join.  the participant sees a message that they were approved to join but then the tab goes blank and they never join the meeting.  In the meeting they just disappear.

The participant is using windows and chrome.

This has been observed on both versions 2.6.12 and 2.6.14.

Has anyone had anything similar occur and is there a fix?

Here are some syslog excerpts:

This is a normal working scenario where the guest/viewer (w_ywpk1b2kvcgy)  is admitted to the meeting successfully

And here is the scenario where the guest/viewer (w_pbotyr3zu5hl ) is admitted to the meeting but never actually joins.  It seems like an issue with the browser client end as the last message referencing user id w_pbotyr3zu5hl is the Updated status=ALLOW message, there are no more log messages referencing user id w_pbotyr3zu5hl  after this message.

I have not been able to recreate this problem but it has happened to viewers joining from the lobby a couple of times now.

[Les Piech]

this has happened again to a participant using a mac on both safari and chrome on BBB version 2.6.14

this seems to happen when the guest policy is set to ask moderator.

has no one else experienced this?

[Les Piech]

  UPDATE:

This is definitely something that occurs on macbooks, in either chrome or safari.   It turns out it DOES NOT have anything to do with guest policy ask moderator as the participant experiences the same problem even when just trying to join a meeting directly.

the participant only sees a screen with 3 white dots running through it.

The javascript console on the participants macbook shows the following error:

Hi Les,

Thanks for digging into this and sharing your findings as you go.  Not sure yet how to solve this, but my first thought is are you able to reproduce this on 2.7 on our demo servers?

Regards,... Fred

Thanks Fred,

I opened another conversation with more detailed errors from the javascript console, since it seems to have nothing to do with the guest policy, but  seems to be a macbook security issue regarding some javascript functions.  Oddly it does work on chrome on iphone, perhaps because chrome on macbook is still a skinned safari (I think?).

I haven't had a chance to upgrade to 2.7 but it's on my list of todos.
