PuTTY - Error: "Software caused connection abort"

Question

I have a problem with my Raspberry Pi 3. When I want to connect to my Raspi, after a few attempts it works, but after while (like 1 minute) it says this error: "Software caused connection abort". I have already added IPQoS cs0 cs0 in SSH config but it didn't work. Any idea how to fix it, please?

Answer 1

Try This

I added this to the end of my /etc/ssh/sshd_config file on my raspberry pi, and it seems to have helped keep my connections stable. I don't remember exactly what it does, but it may help you.

# Added to keep sessions up
# Disabled TCPKeepAlive because it was frustrating
# Send an alive message 30 times before judging the connection inactive and closing it
ClientAliveCountMax 30
# Send the alive messages every 30 seconds
ClientAliveInterval 30
# This should total to 30x30 seconds = 15 minutes before inactive sessions are closed
