The XSRF error historically happens when working on resource constrained hardware. For example, I get it sometimes on my 6 year old laptop, almost always on my crappy virtual machines, but never on my full desktop. The only thing that’s coming to mind regarding the verification error is that we’re back to something not being set up correctly or taking too long on your SFTP server. I apologize if I missed this in your posts, but did you ever update from the beta to a canary version? I ask because if the issue is simply timing related (your SFTP destination doesn’t respond to Duplicati fast enough) then you might find the `--http-operation-timeout` parameter in the the newer canary versions worth testing: > [@Very large backup to B2 failing with "GetResponse Timed Out"](https://forum.duplicati.com/t/very-large-backup-to-b2-failing-with-getresponse-timed-out/1223/3): > > It sounds like you are hitting the response timeout of 10 minutes when fetching the list of remote files. In the canary builds I have added a new option that can change the timeout value: --http-operation-timeout=20m. I have also added the option --b2-page-size=100 that allows you to change the number of files returned in each request. I think this usually helps to have smaller independent backups, as there is less overhead when something needs to be fixed. But I think the problem here is … Though I’ll be honest, I’m not sure that applies to a socket read timeout… --- _[View the full topic](https://forum.duplicati.com/t/solved-sftp-finishes-but-does-not-complete-use-ftp-instead/1456)._
