Chirpstack application Fault

Hi everyone.
I don’t Know why, but I followed all the procedure to install chirpstack under Ubuntu. Everything work fine until modifying chirpstack-application-server.toml where I changed the dsn row with the one written in the chirpstack procedure ( and pur property the jwt secret).
When I close the file e run again start and status systemctl the application goes red in fault. If I change back with the default dsn the systemctl status shows green ad Active but there are some warning errors that I think should be fixed. I didn’t go ahead to see if http://locahost:8080 would work.
Do You have any suggestion? Procedure is clear but error after putting the row below instead of default dsn row:


Thank you,

I solved
Than you
