[Feed problem] JSON dot notation feed with proxy

### Feed URL

https://www.atkinsrealis.com/site-services/api/beyond-engineering?async=1&market=transportation&searchinput=&page=1&content-type=application/json

### Describe the problem

I can not make this json feed work when using a proxy (since the feed is protected with cloudflare), but my proxy (scrapingant) seems to be able to manage it (see capture below from the proxy portail) :
what is strange is that I manage to make it work in FreshRSS if I'm changing the url feed, using the complete curl url provided by scrapingant (but then, the link provided for the article is wrong), so I'm asking myself if there could be a problem with proxy support and Json dot dotation feed
