futeng commented on issue #5206: TooLongFrameException : Adjusted frame length exceeds 5253120: 369295620 - discarded => Error while producing message with TLS on standalone setup URL: https://github.com/apache/pulsar/issues/5206#issuecomment-593189078 I had the same problem, and I solved it. I hope it helps. @iravishah @sijie I configured TLS encryption based on the same [document](https://pulsar.apache.org/docs/en/security-tls-transport/). When using `bin/pulsar-client` to generate data, the same exception occurs, and the log looks like this: ```shell [root@offline126 apache-pulsar-2.4.2]# bin/pulsar-client --url pulsar://offline126:6651/ produce persistent://public/default/test -n 100 -m "Hello Pulsar" 09:47:29.955 [pulsar-client-io-1-1] INFO org.apache.pulsar.client.impl.ConnectionPool - [[id: 0x09a73636, L:/192.168.129.126:49002 - R:offline126/192.168.129.126:6651]] Connected to server 09:47:29.989 [pulsar-client-io-1-1] WARN org.apache.pulsar.client.impl.ClientCnx - [offline126/192.168.129.126:6651] Got exception TooLongFrameException : Adjusted frame length exceeds 5253120: 352518404 - discarded io.netty.handler.codec.TooLongFrameException: Adjusted frame length exceeds 5253120: 352518404 - discarded ... ``` I realized it might be a protocol header issue, so I changed the URL from **`pulsar://xxx`** to **`pulsar+ssl://xxx`**. And it worked. ```shell [root@offline126 apache-pulsar-2.4.2]# bin/pulsar-client --url pulsar+ssl://offline126:6651/ produce persistent://public/default/test -n 100 -m "Hello Pulsar" 10:11:14.695 [pulsar-client-io-1-1] INFO org.apache.pulsar.client.impl.ConnectionPool - [[id: 0x918ed558, L:/192.168.129.126:49218 - R:offline126/192.168.129.126:6651]] Connected to server 10 ... 10:11:15.893 [main] INFO org.apache.pulsar.client.cli.PulsarClientTool - 100 messages successfully produced ```
