Hello!
I had a problem with uploading backup to ESXi 5.5 host. vBackup client show the problem "Unable to upload configuration (VMX) file for new virtual machine to datastore... connection timeout". I tried any ways to recognise the problem: switch off firewall, connect directly to ESXi host over ethernet, but it's not help.
Then I start software tcpview.exe and saw that pscp.exe get connect to 122 port. WTF I thinked, and call to mind that I setup the SSH port 122 to Putty's "Default configuration".
I changed Default config SSH port to 22 in Putty, and It start to upload backup!
I ask to fix this issue at the next release. Maybe there is problem with downloading if default SSH port not set, I have no time to figure it out.
