Liferay 6.2, Amazon S3 TLS version problem, Invalid Bucket: null

Question

Till amazon stopped supporting TLS 1.0 and TLS 1.1 connections our DLFile methods were working fine while adding/deleting files. After the update we started to receive com.liferay.portal.kernel.exception.SystemException: org.jets3t.service.S3ServiceException: The action Create Object in bucket cannot be performed with an invalid bucket: null

and

org.jets3t.service.S3ServiceException:S3 Error Message. -- Response Code: 403, ResponseStatus: Forbidden, XML Error Message: <?xml version="1.0" encoding="UTF-8">InvalidTlsVersionAmazon S3 will stop supporting TLS 1.0 and TLS 1.1 connections....

I've updated the tomcat server.xml file as follows ;

<Connector port="443" protocol="org.apache.coyote.http11.Http11Protocol"
       maxThreads="200" scheme="https" secure="true" SSLEnabled="true"
       keystoreFile="keyStorePath"
       keystorePass="keyStorePass" clientAuth="false"
       sslEnabledProtocols="TLSv1.2"
       ciphers="TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,TLS_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA256,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384"
       compression="on" compressionMinSize="1024"
       noCompressionUserAgents="gozilla, traviata"
       compressableMimeType="text/html,text/xml,application/javascript,text/css,application/json,text/javascript,text/plain,application/octet-stream,image/gif,image/jpeg,image/png,image/x-icon"/>

and still getting com.liferay.portal.kernel.exception.SystemException: org.jets3t.service.S3ServiceException: The action Create Object in bucket cannot be performed with an invalid bucket: null error. Sometimes it just works and sometimes it doesnt.
