Solving Veeam Error: Host with uuid was not found

Today I was upgrading an VMware ESX 4.1 host to VMware ESXi 5.1. I did the update with the VMware Update Manager. After a successful upgrade I tried to backup a VM with Veeam Backup & Replication 6.5. This resulted in an error. See screenshot.

How to solve this problem. I found this easy solution in the Veeam Support Forums.

Go to the license screen in Veeam Backup & Replication. Revoke the license of the ESXi host, and start the backup again. If all went well, the ESXi host gets a new Veeam license assigned and the Veeam backup is successful.

Problem solved!!
