Hello, I'm trying to make a backup to a remote server and it's giving the following error:

Error:
Unable to validate the remote backup. It may not be restored. Error: Failed to exec pmm-ras: Exit code: 1: Unable to set backup sign certificate: Resource temporarily unavailable
Warning:
Unable to save statistics. Error: DB query failed:"SET sql_mode = ''"Error: SQLSTATE[HY000] [2002] Connection refused

Best regards,
Horacio

It could be a network issue, a name resolution issue or your database server simply crashed. Can the issue be reproduced?
