Hey everyone im having some problems with my syncthing i have the latest version of syncthing installed on my pc and the latest version of arkOS on a raspberry pi. i had it working yesterday folders sync and i could edit files on either side. however due to unfortunate circumstances my sd card became corrupted and i had to fresh install ArkOS however now syncthing wont recognise the RPi the picture below shows my pi names ArkOS as disconnected and the adress has a question mark next to it can anyone help? . 
Do you maybe have new keys and hence a new device ID that you need to add to your other computer?
ive used both new device ID’s however i did notice if on syncthing on windows if i leave the name field blank it comes up with a wierd name i dont recognise
