'Unknown Error' during integration setup

[Valdorama]

I'm trying to install this integration but am getting an error when trying to submit the settings (i.e. API key, location etc.).

This is what is displayed:

I am following the instructions to grab the API key from the wunderground.com page.

The log contains the following:

This error originated from a custom integration.

Logger: custom_components.weatherdotcom.config_flow
Source: custom_components/weatherdotcom/config_flow.py:68
Integration: Weather.com (documentation, issues)
First occurred: 08:42:15 (4 occurrences)
Last logged: 08:54:15

Weather.com config responded with HTTP error 400: Bad Request

I have also tried truncating the location coordinates (to just 2 decimal places) but still get the same error.

Just came back and tried this again and sure enough it seems to be working now.

Sorry for not responding sooner - it looks like I didn't have notifications set up correctly, so GitHub didn't tell me that you had opened an issue. Anyway, I'm glad to hear it's working now! I'm not sure why you were getting an HTTP 400 earlier, but it sounds like some sort of temporary issue that fixed itself.

Hey, I'm having the same issue while adding the integration, but the log is different. Could you please look into it?

Logger: custom_components.weatherdotcom.config_flow
Source: custom_components/weatherdotcom/config_flow.py:73
Integration: weatherdotcom (documentation, issues)
First occurred: 1:08:55 PM (6 occurrences)
Last logged: 1:11:26 PM

Unexpected exception
Traceback (most recent call last):
  File "/config/custom_components/weatherdotcom/config_flow.py", line 73, in async_step_user
    raise Exception
Exception

UPDATE Before the error from above I also noticed this error:

Logger: custom_components.weatherdotcom.config_flow
Source: custom_components/weatherdotcom/config_flow.py:68
Integration: Weather.com (documentation, issues)

Weather.com config responded with HTTP error 403: Forbidden

Seems like this is due to wunderground.com is not available in my country, so I got apiKey via VPN.

Interesting, I didn't know that Wunderground had that restriction. This might explain some of the issues that have been reported about API keys not working - maybe they serve different API keys to different countries and some of those keys don't work with Weather.com. I'll add a note about this to the README. Thanks for reporting this issue!

[sviperz]

Yep, but not Wunderground, it's Weather.com. I'm from Belarus. Russia is probably affected too.

[jaydeethree]

I've added some additional info about this in the README. Thanks again for reporting this!

[sviperz]

Sure, you're welcome!

There is one more thing that is strange. I added routes to send weather.com and wunderground.com traffic through VPN located in the area without restrictions. And curl shows no 403 errors now (which it does without VPN) when I check from within HA, but still I'm getting the same Weather.com config responded with HTTP error 403: Forbidden message in the log and can't add the integration.

All of the endpoints used by this integration are on api.weather.com - can you try connecting to that and see if it works for you? You may need to add a special route for that domain also.

[sviperz]

Cool, it works now! I could have checked it in the code 🙃️ Thanks!

[jaydeethree]

Awesome, I'm glad that worked!

[sviperz]

Finally, this is a weather integration that has everything I need. Thanks again!
