I am unable to access my server anyhow?
I think that someday, I restarted my server using the Digitalocean control panel probably due to which this problem started.
The current situation- I am not able to SSH and also unable to connect using Control Panel consol window. to my droplet
I expect that some files related to ssh might have got corrupted for me not being able to connect via ssh (It shows "Connection closed by <ip> on port 22"). For the second case, the reason might be the fact that my office network only allows connections on port 80, 443 and 22 only (It shows a black screen with "Server disconnected (code: 1006)").
So what should I do now to get access to the droplet.
