Hello @AndreyKravtsov    Please refer to the article below to Integrating Apache NiFi and Apache Kafka [1]   [1]  https://community.cloudera.com/t5/Community-Articles/Integrating-Apache-NiFi-and-Apache-Kafka/ta-p/247433   This example is with the PLAINTEXT Kafka protocol. It looks like you are using SSL/TLLS for kafka. You should check whether you are using SSL or SASL_SSL protocol for kafka from CM >> Kafka conf and created a StandardSSLContextService controller setting and update with Kafka Keystore and Truststore details. You can refer the below article for details [2]:   [2] https://community.cloudera.com/t5/Support-Questions/Need-help-with-SSL-config-in-Nifi-ConsumeKafka/td-p/320594   Additionally, refer the following articles for more details:  [1] - https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-standard-nar/1.17.0/org.apache.nifi.processors.standard.InvokeHTTP/index.html [2] - https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-ssl-context-service-nar/1.20.0/org.apache.nifi.ssl.StandardSSLContextService/index.html   If this information helped you, then it will be appreciated if you will take a moment to click on KUDOS 🙂 ...
