Outdated SMB client: SharpCifs.Smb.SmbException: This client does not support the negotiated dialect. #3780

Closed reijin90 closed 1 year ago

Hi!

It seems that emby uses an outdated SMB client protocol which does not support current SMB implementations. I was not able to find out which library is being used specifically, but this one, which seems to exhibit the exact same error is deprecated and points to a new implementation which supports current SMB versions: https://github.com/ume05rw/SharpCifs.Std

Hi, this has been updated in the upcoming 4.8 server release, but we still suggest mounting to the local system if you can. Thanks.
