No data via MQTT #49

Closed ndrtrp closed 6 months ago

ndrtrp commented 6 months ago

Since yesterday, I no longer receive any values via the EU-Zendure MQTT server. I use the MQTT information for my Home Assistant. Now I am not receiving any values in the Home Assistant or in the MQTT Explorer. I noticed the problem after I had to restart Home Assistant. Querying the appkey and appsecret via the command line works and I get the expected response from the server. Unfortunately, I now have no idea where the problem lies. Is the MQTT server currently overloaded? Have I been blocked? I am still receiving data in the app, even if there are occasional interruptions in the energy statistics.

Okay, so after really trying everything to narrow down the problem, perhaps the most obvious thing was the solution in the end. I use Unifi and had geoblocking rules (both directions) active for some countries (including China) in the security settings. I somehow didn't assume that the EU server was located in China ;-). Well, I have now only blocked the incoming traffic, now I get a connection and data again. Alternatively, you could also remove China from the list. I'm still not sure why it worked before and not since yesterday, but for now it's solved, at least for me.
