@Augustin Lafanechere (Airbyte) Yes I tried this but IT would not work. I would get a

error in that case.
enabledTLSProtocols=TLSv1.0
instead but I would then get a `No appropriate protocol (protocol is disabled or cipher suites are inappropriate)`error.
Ok I fixed the issue by setting the
verifyServerCertificate
&
useSSL
JDBC params to false and succeeded upgrading to version 0.5.6.
