11.0.1 Rpi4 - "No Route to Host" when accessing SMB share from another rpi4 box

  • Hi. I am using an rpi4 (rpi4a) as libreelec player and another rpi4 (rpi4b) as a file server. I also have a pc running pfsense as the router for the entire network

    On the libreelec box, I have added the rpi4b as a file source, using the box's host name "rpi4b". It works fine before

    I think the problem started two versions ago. Whenever I tried to access rpi4b, the interface took like half a minute, then present me with a "No Route to Host" error message. If I added rpi4b as an SMB source using its IP address, I can access it fine in libreelec

    Libreelec SMB minimum version is set to v1 and I didn't set the versions of SMB share in rpi4b (default)

    I don't have problem using hostnames for other network shares (a few WD Mybooklive drives, an old Asus router and my personal PC)

    The funny thing is I was able to mount the SMB shares of rpi4b in rpi4a using the instructions from https://wiki.libreelec.tv/how-to/mount_network_share using the host name

    One of the .mount file:

    rpi4a:~/.config/system.d # cat storage-videos-rpi4b-mybook8.mount

    Code
    Pinging rpi4b from rpi4a works fine:
    rpi4a:~/.config/system.d # ping rpi4b
    PING rpi4b (192.168.0.25): 56 data bytes
