Hi

Can someone help me?
This is the error when I try to backup

Thanks for help

Hi Matheus,

My guess would be that antivirus or a firewall is preventing the agent from working properly.
Or in rare cases, it could be IPS (intrusion prevention system that decrypts SSL, inspects it and re-encrypts it on the fly).
Here's what has to be reachable by the agent:
