upgrade 9.5 SQL connection problem

[allankjaer]

I was upgrading Veeam ONE from 9.0 update 1 to 9.5, and encountered a problem that the upgrade wizard could not connect to the SQL server (using the default SQL Express 2012 SP3.)

After some troubleshooting I found that I had disabled SSLv3 and TLS 1.0 on the server.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Server]
"Enabled"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 3.0\Server]
"Enabled"=dword:00000000

I change the 2 values to: dword:00000001

Rebooted and upgraded without problem, not sure if it needs SSLv3 or TLS 1.0.

Allan, could you contact Veeam support to provide logs for investigation?
Thanks

Sorry. This was in a test environment, that is deleted now.

I only checked/edited the settings in the production environment, before upgrading. without problems.

Veeam ONE service account requiremens were changed in v9.5:

or the easiest way is to provide sysadmin role on SQL server for ONE service account during upgrade.
