The upload for BIG-IP-Next-CentralManager-20.2.0-0.5.41-Update.tgz keeps timing out, so I've not been able to upgrade. My "session" times out and I have to login again.

    Hi TimRiker have you checked to see if any traffic is transiting between your client and CM when you initiate the file upload? I found in tcpdump capture that CM was instructing me to fragment. On my mac, I had to disable tso in the tcp settings to make that happen:

    # Add this line to /etc/sysctl.conf

net.inet.tcp.tso = 0

# or for toggling purposes

sudo sysctl -w net.inet.tcp.tso=0
sudo sysctl -w net.inet.tcp.tso=1
