I’ve got SMB connection problems since Infuse use a new SM library…
Problems is happening in both TVOS and ios (I’m using the last publc beta of 11.3 on tvos).
I’m using a Buffalo NAS.
Every time my Apple TV or iPad is going to sleep or is powered off, the next time I’m using infuse He can’t access to my SMB folders.
A reset of the device is needed…
Have you used the new feature in the very latest release 5.6.10 which allows you to select different versions of SMB, including using the old ‘legacy’ version?
I suggest that you go to settings and try changing the version of SMB to use on you SMB connection(s) and see if it makes a difference.
