I have Dude running on hex s on microSD card. the card is formatted in ext4 format.
been running dude for a year on usb drive - the drive died. then i changed to microSD the last ~6 months. it stopped working last month (i rarely use it, just for checking traffic if there's some problems). dude itself is running, service is running, but database is empty. microSD is OK, files are on it, does not show any error but everything is empty. for the DB file it shows that it has been created every time i restart the dude service. (today at 11.30)
this is the 2nd time it happened. i have around 30 devices in monitoring and is PITA to set it up every time.
why TF is this happening? How to recover database with all devices and settings?

i got tired of setting this up again, i'll check prtg free version.
