Hi lottolearn,
Is there something specific related to the mounted disks (e.g. file system)?
Can you please send logs to help us with the investigation? For now, server-side logs will be enough. You can collect the logs as described in this article: https://knowledgebase.nomachine.com/DT10O00163#1.3
Please submit them to forum[at]nomachine[dot]com putting the title of your topic as the email subject.
Thanks!
