You got network bandwidth problems. If you are trying to do 5500 bitrate, add 20% above that on your Internet service for headroom.
5500 bitrate x 20% = 6600 bitrate
6600 bitrate = 6.6 Mbps upload speed
Is your Internet service giving you over 6.6 Mbps sustained and above?
Are there one or more devices on your local area network (LAN) that is uploading/downloading at the same time?
Are your Ethernet cables and connection to the Ethernet ports good?
