Hello,

We do not have any kind of connection time limits for external connections, any limitations in this regard would come from your own application, or the service you are trying to connect to.

I'll go ahead and open this up to the community, they may be able to help you debug where your connection time limits are coming from, because they are not on the Railway platform side of things.

Best,

Brody

Hi,

A SocketTimeoutException usually means that your application cannot establish or complete the connection to the external API within the set timeout. Since Railway does not impose connection time limits, the issue is likely due to one of these reasons:

• The external API might be blocking Railway’s IPs or has regional restrictions.

• The API response time might be longer than your configured timeouts (make sure to increase both connection and read timeouts).

• There could be network issues or SSL/TLS handshake problems.

I recommend testing connectivity directly from your Railway deployment shell using a command like:

curl -v https://external-api-url

This helps verify if the API is reachable from Railway’s environment.

If the API is reachable locally but not from Railway, contacting the API provider to whitelist Railway’s IPs or clarify network policies may help.
