I am having some strange behavior when sending files via macOS Messages app and was wondering if other people have this working. When sending on our internal network, file transfer fails. However sending from external to internal works correctly. When using the spark client file transfer works just fine, so I would assume it’s a port of a config on the macOS client side, but am having trouble sorting it out.
We run Openfire in AWS with ports exposed as needed. Everything works great, except for file transfers.
If anyone has this working and could give me any ideas, I would be very grateful.
