Deactivating license failed

[jniino]

Hello, I bought new QNAP NAS, so I deactivated MinimSerevr on old QNAP NAS.
But It fails. Could you please deactivate my first license of minimserver?

Error message is as follwos.

Unable to connect to license server:javax.net.ssl.SSLHandshakeException:@sun.security.validator.ValidatorExce​ption:PKIX path building faild:sun.security.provider.certpath.SunCertPathBuilderException:unable to find valid certification path to requested target; Unable to connect to license server:javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.securty.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target.

And it became starter license.
Device: QNAP-TS228
OS:4.3.6. 2241

I checked license tab on new machine's minmserver.
It shows 'You are using 2 of 3 license activations (click here for details)'.

Thank you.

This sounds like the problem described in this post. I was aware that it affects the QNAP TS-109, 209 and 409 but I wasn't aware that it also affects the TS-228. I have deactivated your license as requested.

I confirm that my license of first one was deactivated.
Thank you.
