hey.

this seems to be a problem regarding your BBB installation.  
do you really need it? how is it setup?

further on it would be a nice idea to ask someone over there at ucs-forum as well… since you seem to be running their system

Thank you so much for you reply,

Sorry, I don’t know what is the meaning of BBB, I’m just IT admin and it installed automatically with UCS and Nextcloud.

Thanks for your advice.

BBB= Big blue button… an additional chat/video-software-connector that is available (for free) through the appstore…

if you don’t have your own BBB-Server you prolly can’t use this app.

so best would be to just disable said app and then de-install/remove it.
