Network error while attempting to run command 'validate'

Due to the issue with MongoDB mentioned here I have to run Validate command and check collections, but command is being executed really long time and as results I’m getting error:

network error while attempting to run command ‘validate’

Mongo shell and server versions are the same. Connection is done by using TLS . Validation is executed on the same host where server is running to avoid network issues.
Is there any way to get validation results even if CLI client is disconnected? Is it stored somewhere? I’m kinda frustrated, no docs about it. Or maybe there is a way to avoid this network issue?
