dzvents entsoe http request failing

[willemd]

For years I have been running async http requests from dzvents to get entsoe prices through their API, until Sep 7th...

Now I just get a response 403 "Forbidden" instead of a list of prices.

I have tried the following analysis:

1) run the same http command from a PC browser : no problem
2) run the same http command with a curl call (on the command line) on the domoticz machine : no problem
3) run the same command with a async shell request running curl from dzvents : no problem (so this is a workaround for now)

so it is only the async http request from domoticz that is triggering an error.

The problem first occurred after the entoe migration to a new platform. For some reason this triggered an incompatibility with the async http request from domoticz. I don't have any info on details of the entsoe migration. The feedback shows that Microsoft-Azure-Application-Gateway/v2 is involved in the creation of the 403 response.

I don't see much usefull info in the domoticz log that could help solve this. Just HTTP/1.1 response: 403 ==>> Forbidden

Anyone with similar experience? Any clue how to get the http request working again, instead of using the shell command as a workaround?

What version of Domoticz are you on? Still 2024.1 as in your profile?

No, latest stable 2026.3

I think my question can also be "how is the full http get command that dzvents is sending with async http different from curl" ? That difference triggers a different reaction from the server.
