I work with Telerik WPF 2016.R3 and since this morning the provider OpenStreetMap doen't work anymore
I check with the site of OpenStreetMap and the request done by the provider with my navigator and it works well but when my application is calling OSM to get tiles it returns an HTTP error 429 : too many requests
This problem only happens since this morning, last week it works perfectly.
All our applications use this provider to show the map, and so all our clients have the problem !
From my first investigations:
- the Telerik provider use HTTP protocol but when using in my navigator it redirects automatically in HTTPS (I don't know if it has an impact)
- I tried to create a new provider using Telerik Map Source of OSM to force the HTTPS but the same HTTP Error 429 happens
- Using Fiddler to check the request I succeed to have a good response when I added a User-Agent Header in the request
- using the latest demo (WPF 2019.R3), in the sample of Provider Bing and OSM, Bing works correctly but not OSM (the same HTTP error 429 happens)
Do you have any idea of what's happening and how to fix it please ?
PS : I can't update my version of Telerik because there is a very big impact on the map layer management done in v2017.R3 that cannot match our layer management in our application.
