Hello, I just flashed my Heltec v3 with 2.2.24.e6a2c06 Beta.
I’ve noticed some issues with using MQTT and Wifi.
It will not connect my local MQTT broker when using Wifi. Sometimes a message will be published stat/{ID}/offline, but that’s it.
However, when I disable Wifi and connect to it with Bluetooth, enable “proxy to client” it works just fine.
I have a TBEAM on the same network & broker, using the same version of Meshtastic and it works just fine.
I just flashed another Heltec v3 node with the same firmware, and same issue persists. I can confirm that MQTT is working fine with a TBEAM using either of the credentials I used for both Heltecs with the same firmware version.
I’m using a Heltec lora V3 on wifi with MQTT and no problems. The wifi signal is fairly weak compared to a phone or laptop though. I’m on 2.3.1 but the previous versions work too…
I just updated to 2.3.2.63df972 Beta and same issue.
I pulled the logs from it:

Seems like Wifi is disconnecting for some reason? Not sure what Err 119 or 128 is. I don’t think anything else is having Wifi issues. I run a few Tasmota sensors and that. I have a Lillygo T-Echo and it seems to run fine, but none of the 3 Heltecs are.
with ver 2.3.4 i can connect for less of an hour than stop to talk on wifi.
After the wifi is configured i can connect to the heltec by ip acquired via dhcp but after about 1 hour became unreacheble
