@Herrera Gonzalez, Jose Wilfredo Thank you for posting your query on Microsoft Q&A forum. Happy to assist!
From the screenshot shared, I understand that Azure Site Recovery Unified Setup is failing with "Download MySQL - Failed" and validating server configuration - Failed"
Please ensure that you are installing 9.40/higher version of MicrosoftAzureSiteRecoveryUnifiedSetup.
Allow communication to all of the Azure URLs over HTTPS (443) port - https://learn.microsoft.com/en-us/azure/site-recovery/vmware-azure-deploy-configuration-server#verify-connectivity
Update:
If you have proxy configured, Azure URLs over HTTPS (443) port - https://learn.microsoft.com/en-us/azure/site-recovery/vmware-azure-deploy-configuration-server#verify-connectivity should be in bypass list.
If there is no proxy, ensure Azure URLs are all whitelisted.
