Trading API 403 - Cloudflare WAF blocking POST to /pub/v3/bets/place from Railway/AWS IP

[bemfilo-code]

Hi Cloudbet team,
I'm getting HTTP 403 Forbidden on POST requests to the Trading API. Support chat directed me here.
Details:

Endpoint: https://sports-api.cloudbet.com/pub/v3/bets/place
Blocked IP: 44.221.159.115 (Railway / AWS us-east-1)
CF-Ray: 9f7c9bc439416dc6
GET requests to /pub/v1/account/balance work fine (200) with the same API key
Only POST to bets/place returns 403 with Cloudflare HTML block page

Request headers:

Content-Type: application/json
X-API-Key: [trading key]

Payload format: standard bet placement with marketUrl, outcome, price, stake, currency, referenceId
Support confirmed the setup looks structurally correct — likely a WAF rule or location flag on the datacenter IP range.
Could an engineer review and whitelist IP 44.221.159.115 for Trading API access?
Thank you!
