  3. In Windows event logs, you see this error:
    Error 0x294000d: Socket bind error
    | trace level: error
    | line: 0x18073c0bca1ee95e
    | file: k:\238\http\server\server_impl.cpp:806
    | function: Http::Server::InstanceImpl::Run
    | Address:
    | Port: 8089
    | $module: http_vsa64_238


Port 8089 is already in use by vCenter server.


The issue has been fixed in Update 1 of Acronis Backup 12.5, port 8089 has been changed to 30500. Please update the software to the latest build.
