After I have found out too late that the SparkWeb needs more ports than port 443, I urgently need another possibility.
Our external users have merely port 80 & port 443 openly.
I need therefore urgently an alternative for a web client who communicates exclusively about one of both ports with Openfire.
I have had a look at some JABBER servers, however, comes on no solution.
It would be fantastic if somebody could help me here in a contemporary way.
Thank you so much,
