Black screen after update to 2.7

[Zbigniew Łęski]

Hi

We had perfectly working BBB v. 2.5, and unfortunately we've decided about upgrade... Everything was fine. No errors during upgrade proces. No errors on bbb-conf --check and everything active on bbb-conf --status. Our moodle can see BBB and can play old recordings. But when trying to start new meeting we have only black, empty screen - no matter if we try from moodle or from Greenlight...

The only errors on server are in /var/log/nginx/error.log:

Any ideas what is wrong?

Did you rerun the command to set the url? It fixed stuff like this for me

Yes - I've tried to rerun the command to set the url. Still the same...
