@Danubiustest Thanks for reaching out to us, are you mentioning your website using Bing Search API?
Bing Search APIs are moving from Cognitive Services to Bing Search Services. Starting October 30, 2020, any new instances of Bing Search need to be provisioned following the process documented here. Bing Search APIs provisioned using Cognitive Services will be supported for the next three years or until the end of your Enterprise Agreement, whichever happens first. For migration instructions, see Bing Search Services.
Please create a new resource for usage as this guidance - https://learn.microsoft.com/en-us/bing/search-apis/bing-web-search/create-bing-search-service-resource
Please let us know how it works, I hope this helps.
Regards, Yutong
