I am facing a problem while trying to SSH a DO droplet. It is running 4 Python scripts fetching data via API and storing in MySQL(running on same Droplet). It had no issue when I was running 2 Python script but I started facing issue of SSH when I ran 4. Intially it gave the error:
'shell request failed on channel 0
and I was unable to login. When I enabled the verbose mode after sending -v switch it took a while and then logged in with the following info:
