Hey guys,

BBB 2.4 rc2 works like a charm, however I'm receiving a lot of nginx errors in my log file /var/log/nginx/error.log. For example:

2021/10/11 14:16:24 [error] 32182#32182: *255 connect() failed (111: Connection refused) while connecting to upstream, client: 93.180.105.130, server: bbb.vokabula.com, request: "GET /html5client/resources/images/whiteboard-cursor/pan-closed.png HTTP/1.1", upstream: "http://127.0.0.1:4102/html5client/resources/images/whiteboard-cursor/pan-closed.png", host: "bbb.vokabula.com", referrer: "https://bbb.vokabula.com/html5client/join?sessionToken=rsmv2w3wx4hagtih"

I'm just looking someone to point me to the right direction where to look, since I'm aware this is not a nginx help group.
