Hi Railway Support,

I’m encountering an issue where outgoing HTTPS requests from my Railway-hosted backend to PayPal’s live API are being blocked.

When my server calls:

POST https://api-m.paypal.com/v1/oauth2/token

PayPal returns:

403 Forbidden  
Error 54113  
Varnish cache server (cache-ams...)

The same exact code and credentials work perfectly when run from my local machine, but fail when executed on Railway.

It seems PayPal’s edge (Varnish/CDN) is rejecting requests originating from my Railway deployment IP or region.

Could you please check whether:

• The Railway server’s outgoing IP address or egress region might be blocked or restricted by PayPal?

• It’s possible to change the egress IP / region or whitelist PayPal’s API endpoint (https://api-m.paypal.com) for outbound requests?

For reference, the request uses standard HTTPS with Basic Auth and JSON — no unusual headers or payloads.

Thanks for your help!
