That is a special error which is perfectly correct for trying to mount
IPC$ from the filter with ssnLimit = 1.

If you provide a stack trace it will probably show you what is trying
to access IPC$.

It could be the DFS code. Try disabling domain-based DFS in
conjunction with ssnLimit = 1 with:

  jcifs.smb.client.ssnLimit = 1
  jcifs.smb.client.dfs.disabled = true
