Hi Railway Team,

DNS resolution for api.ebay.com is failing inside Railway runtime.

This is not an application code issue. I created a fresh Railway service and used only this start command:

python -c "import socket; print(socket.gethostbyname('api.ebay.com'))"

It fails with:

socket.gaierror: [Errno -5] No address associated with hostname

I also tested:

python -c "import socket; print(socket.getaddrinfo('api.ebay.com', 443))"

It fails with:

socket.gaierror: [Errno -2] Name or service not known

But this works:

python -c "import socket; print(socket.getaddrinfo('www.ebay.com', 443))"

It returns IP addresses successfully.

So the issue is specific to resolving api.ebay.com / global-api.ebaycdn.net from Railway runtime.

My production FastAPI service is failing eBay OAuth token calls to:

https://api.ebay.com/identity/v1/oauth2/token

Error from production logs:

httpx.ConnectError: [Errno -2] Name or service not known

/etc/resolv.conf inside Railway container shows:

search internal railway.internal

nameserver fd12::10

Please check DNS resolution for api.ebay.com from my Railway runtime/region.
