Client cannot connect to server

i made a test install with my client to one server

when i start the client with command

i have the message “cannot load password”

the test command
sudo start_urbackup_client --loglevel info --no_daemon

gives me that :

the urbackup_client_gui

gives me a loop of : could not load password file

there is no specification of what file we are talking about

what is rare as it was working before

here ia have a bit mit information :

sudo start_urbackup_client --loglevel info --no_daemon

the server can list the client but cannot start the backup

the client gui gives me :
startin backup : Could not start backup, because no backup server was found
status : There was an error. Currently nothing can be backed up
client logs: empty

what does this meassage password wrong means ?

i see nothing in the documentation

I had the same issue.

Changed the permissions of the pwd.txt.

chmod 777 /usr/local/var/urbackup/pw.txt
