This article applies to: on-premises deployment of Acronis Cyber Backup 12.5
Proxy with authentication is not supported in on-premises deployment of Acronis Cyber Backup 12.5.
If proxy is enabled in your environment, you may face errors when configuring backup to Cloud (errors 504, 403 etc) and when checking for updates. If you intend to use these features it is recommended to disable authentication or avoid using proxy entirely.
The following Acronis products support proxy with authentication:
- Acronis Cyber Backup Cloud
- Acronis Cyber Backup 12.5 - Cloud deployment (more information on difference between Cloud deployment and on-premises deployment can be found here; instructions for setting up proxy are available here)
