'Unable to login to digital ocean ubuntu after some time

I'm working on a laravel project. I hosted it on digital ocean, ubuntu server.

After some days i run the below command $ php artisan serve on the server, just like I'm on a local host. Since then i could not access the ssh again

Whenever i try to access the ssh i get this error from git bash

command

ssh [email protected]

Error message

kex_exchange_identification: Connection closed by remote host
Connection closed by 888.00.00.888 port 22

Is there anything I can do except dropping the entire droplet and creating new one. The website is still in development mode, but what id=f this occur in live version.
