SSH stops working after upgrade to Ubuntu 18.04 on AWS Lightsail












0















I had a working ssh for my aws lighsail instance.



I upgraded by ubutu from 16.04 to 18.04 using $ sudo do-release-upgrade.



Upgrade went smoothly and asked for reboot in the end to complete the upgrade
After that I have lost the ssh connect and since then reconnect does not work.Tried both putty and web ssh.Not working.
I can see even sftp filezilla has stopped working.



The instance is running (in aws lighsail console) and I can also access the lightsail website that means upgrade has completed successfully and not crashed.



I have checked the lightsail networking tab and port 22 for ssh is enabled.I did a remove and add but did not help.



Please help



Regards
Ash
