I'm using a RPI4 8GB which is on 24/7, connected only via an ethernet cable, with 12 Beta 2, after running for 24 hours I'm unable to connect using the host name from any linux or android devices; if I go into the Libreelec Configuration Addon the top option on the connection is connect rather than disconnect, implying it's not connected at all, but when you choose the connect option it results in a Input/output error - see attachment log file snippet; the RPI4 is however still accessible using the static IP Address it has been assigned, so it is connected but somehow has lost the ability to be access via the hostname , the only way I've found to resolve the issue is to reboot the RPI4 and all then works until a day passes and then it is again unreachable via the hostname until a further restart; using 12 Beta 1 or 11.0.6 this didn't happen
