Host Key verification Failed

If you are seeing below Hot Key Verification Failed Issue - 



Then it's basically happen when machine has changed and your old keys are saved in your old system.

You have to follow the instruction given at the error messages - 
"Offending ECDSA Key in "C:\\Users\\Rahul/.ssh/known_hosts:2"
Do follow the below steps,
  1. While opening command prompt get inside known_hosts file using,
    notepad .ssh\known_hosts 
  2. After opening known_hosts file, remove/delete the line no "2". And save it back. If in your case it's :3 or any other number like :10 - You need to delete that line. Here in the screenshot it's line no 2 let's remove that & now save and close it
  3. And try to access it with, ssh -p command now it'll work fine.


Even after that if you are not able to solve - please drop a email at itsupport.
