Upon upgrade from vRanger 5.2.0 to 5.5 backups that were previsouly working hang at 24%.
vRanger Automatic Transport Selection is wrong or misconfigured
1. Edit backup job(s) and click next until the "Transport Selection" window appears
2. Uncheck the circle "Automatic Transport Selection"
3. In most cases not all, uncheck circle "On vRanger virtual appliance" and instead select "On this vRanger Machine"
Please note that in most cases after upgrade vRanger Virtual Appliances are not used for backups b\c they were not available until vRanger 5.4.0 to be used for backups. Depending on the environment in some cases also deselecting the "advanced (SAN/ HotAdd)" especially if still runnning ESX hosts and have "LAN" selected instead.
