I am using FileZilla to connect my Ubuntu server using the PPK file but every time I am getting the below error. Yesterday it was working but today I tried several times but not working.

I have checked my SSH and it's working perfectly. Any idea why I am getting this error?

Have you checked `/var/log/auth.log` on the server ?

@Marco, What i have to check in that?

The log should contain the reason why the server refuses the connection.

This part of the log contains your ssh login to grab the log, which is useless. We need the part of the log from the time the Filezilla connection failed.

@Marco, too much code in the /var/log/auth.log server and this portal not allowing me to add

You can upload more data to a pastebin, for example [pastebin.ubuntu.com](https://pastebin.ubuntu.com/) and post a link to it in your original question.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
