Hello and apologies if this is the wrong place for this question.
I am having an issue with a (Python) paho-mqtt client connection receiving a [SSL: TLSV1_ALERT_INTERNAL_ERROR] tlsv1 alert internal error from Chariot (and crashing) when the “Stop server” button is clicked (or the service is stopped) on the Chariot broker.
On the Chariot side I see the error:
“Error closing inbound of SSL/TLS connection with ID ######: closing inbound before receiving peer’s close_notify”
Normally, my Python client will “walk” to the next available server if the server it is connected to goes down. This is tested to be working on:
- Chariot without SSL
- Mosquitto broker with/without SSL
- Chariot with SSL *** ONLY if the docker container containing Chariot is restarted, or if access to port 8883 is blocked via firewall ****
There seems to be something in the Chariot shutdown process that is causing this error. Preliminary Googling seems to suggest either a bug in JVM 11, or a mix-up in the order of closing the request and the reader.
- Both Linux and Windows Chariot v2.2.3
- Python client is using Open SSL 1.1.1q and connected via TLSv1.2
