Why do I get a timed out error when calling a REST API?

Getting timedout error when calling a rest api. Already set maximum value for timeout. Also implemented retry for 3 times by catching the exception. Error occurs for only few calls to rest api, though the body is same for every call. The 120,000ms limit applies to all callouts in the same transaction.

Why do I get system.calloutexception : read timed out?

I’m frequently getting the error “System.CalloutException: Read timed out” on an HTTP Service (RESTful) call I am making from an Apex class. It doesn’t appear to be a proxy/firewall issue as I *am* able to get a response. I think I just have a slow server on the other end.

What causes a read timeout on a socket?

Timeout here would typically be tomcat connector -> connectionTimeout attribute. Correct. Client has a read timeout set, and server is taking longer than that to respond. No. That would cause a timeout at the client. One of the threads i went through, said this can happen with high concurrency and if the keepalive is enabled.

What does the read timeout attribute in Java mean?

Is there any way to change system.calloutexception?

You may be able to write a retry into your code, so that when you do catch () a timeout you can try one more time. I was afraid of that. When the Callout times out, the operation has already been performed on the other end and I’m just waiting for the response. If I make the call again, I will get duplicate transactions.

Generally speaking, the 303 status code allows a REST API to send a reference to a resource without forcing the client to download its state. Instead, the client may send a GET request to the value of the Location header.

How to reduce client response timeouts in azure?

Another potential mitigation to consider is improving processing times for your backend APIs. One way to do this is by configuring certain APIs with response caching to reduce latency between client applications calling your API and your APIM backend load.
