Something happened with my RPi recently – I don’t know exactly when it happened – where I couldn’t access my SMB shares. I had a look here and saw references to such problems for the Vero, but didn’t see anything that matched my issue with the RPi. I tried a solution posted in the Vero section that worked for me, so I thought I’d report it here.
I navigated to Settings>Services>SMB Client and noticed that Minimum protocol version was set to none and maximum set to SMBv1. I changed the maximum to SMBv3 and that solved my problem. I can now access all my SMB shares.
Did something get changed in a recent update that caused this problem for me? I’m just curious at this point.
