Hello, I have a Tor Bridge and it worked well (thanks also for your kind support) but it doesn't work anymore after I tried to move it. Basically I copied the 'Keys' folder (at /var/lib/tor/keys) on a USB flash drive. After that I put the folder into the /var/lib/tor folder of the new device (deleting the pre-existing "Keys" folder). But I receive these errors on syslog (/var/log/syslog):

(i'm using a PC with Kubuntu 21.04 and I followed this guide for the setting up: https://community.torproject.org/relay/setup/bridge/debian-ubuntu/)

What can I do to solve these errors?
