MQTT + IPv6 enabled breaks MQTT completely #308
Description
Steps to reproduce:
- Have IPv6 address on Go-E PRO Cable
- Have IPv6 address on MQTT server
- Connect Go-E PRO to MQTT server
Expected results:
- MQTT messages visible on server
- MQTT status messages reported by charger reflect reality
Actual results:
- No MQTT messages visible on server
- No connection attempts visible in packet capture
- MQTT status keys (
mce,mcc,mcca,mcs,mlr) all indicate that everything is totally fine
I confirmed this is a problem with IPv6 by blocking the AAAA record for this specific device. When I do this, it falls back to IPv4 and everything works as expected.
I'm running firmware 60.3. I haven't noticed this issue for a long time and only installed 60.3 recently, so it's possible it was introduced in that version.
