regiskuckaertz opened a new issue, #1910: URL: https://github.com/apache/pekko/issues/1910
I have a cluster of 6 nodes using classic remoting, 4 of which are running on pekko. It's working fine, except that every now and then it seems messages are sent in the clear, e.g.: ``` 2025-06-18 19:00:34,953 WARN [PTS-pekko.actor.default-dispatcher-17] o.a.p.r.t.netty.NettyTransport NettyTransport(pekko://PTS) - Remote connection to [/***:46890] failed with io.netty.handler.ssl.NotSslRecordException: not an SSL/TLS record: ... 2025-06-18 19:00:34,958 WARN [PTS-pekko.actor.default-dispatcher-28] o.a.p.r.t.netty.NettyTransport NettyTransport(pekko://PTS) - Remote connection to [***/***:1603] failed with javax.net.ssl.SSLException: Tag mismatch 2025-06-18 19:00:34,958 WARN [PTS-pekko.actor.default-dispatcher-28] o.a.p.r.t.netty.NettyTransport NettyTransport(pekko://PTS) - Remote connection to [***/***:1603] failed with io.netty.handler.ssl.NotSslRecordException: not an SSL/TLS record: ... 2025-06-18 19:00:34,959 WARN [PTS-pekko.actor.default-dispatcher-28] o.a.p.r.ReliableDeliverySupervisor akka.ssl.tcp://PTS@***:1603/system/endpointManager/reliableEndpointWriter-akka.ssl.tcp%3A%2F%2FPTS%40***%3A1603-7 - Association with remote system [akka.ssl.tcp://PTS@***:1603] has failed, address is now gated for [5000] ms.

These messages only come from pekko nodes. Have you seen this before? I'll increase the log level to see if I can get more details. -- This is an automated message from the Apache Git Service.
