Challenge

There are several issues could occur after disabling TLS 1.0 protocol on the Veeam ONE server:
  1. Veeam ONE 9.5 server may lose a connection to the SQL Server for runtime operations
  2. Veeam ONE 9.5 server may lose a connection to the SQL Server during the initial installation
  3. “Veeam Licensing” web server is unavailable when only TLS 1.2 protocol is enabled
  4. Veeam ONE Reporter website doesn’t work when only TLS 1.2 protocol is enabled

Cause

TLS 1.0 is no longer officially supported.

Solution

1. Veeam ONE server may lose a connection to the SQL Server for runtime operations
Solution: install an updated SQL Server Native Client (11.0) to the Veeam ONE server machine

Solution: use https://www.veeam.com/KB2265

3. “Veeam Licensing” web server is unavailable when only TLS 1.2 protocol is enabled
Solution: enable TLS 1.1

4. Veeam ONE Reporter website doesn’t work when only TLS 1.2 protocol is enabled
