Hi everyone,

I’m running into an issue with an HTTP GET request in Power Automate. This flow used to work fine a few weeks ago, but now the same request consistently returns a 403 Forbidden error.

I already tried:

Adding a custom User-Agent header to avoid being detected as a bot
Testing different standard headers
Recreating the HTTP action

None of these attempts made any difference and I still get a 403 response.

Because the request used to work and nothing changed on my side, I suspect the target website may have recently added stricter bot detection, firewall rules, or IP blocking for cloud traffic.

Has anyone experienced something similar?

Do I need to add additional headers (cookies, referer, origin), or is it more likely that the site has started blocking Azure/Power Automate IP ranges?

Any suggestions on how to troubleshoot this or confirm the cause would be greatly appreciated.

Thanks!
