Hi! I’m trying to send an announcement to users in group trust level 0 but get error 502 in return.
> Failed to load resource: the server responded with a status of 502 ()
Where should I look to see exactly what causes this error? How to pinpoint it? Can it be that number of users in that group is a problem? (~32k users)

Indeed. IMHO if you want to get something out to all members it is better to have a global announcement or banner topic. If the intent is to email all members, export the list and use an email service.

Oh well … life can’t always be easy, right? 😉
