Hi Olivia, Could you try this with latest code? We’ve had a number of fixes go in over the past months, including the one that you’ve mentioned lower. Hard to say if the issue has been fixed as tls might ignore the dequeue notifications from tcp for some reason. If I were to guess, this [1] might help.
