The connection has timed out

Basically I have an application that calls an api. Occasionally I would receive a timeout error.

So I checked under service center->monitoring->integrations (No error)

Then I checked under service center -> monitoring -> Errors and I found the connection timeout error.

Does the following error mean something is wrong from outsystems end instead of my api?

Have a look at the following post



I have the similar log message which occurs during a server action with a few REST calls in sequence (about 15 sec and 5 second response times).  No reported error in the Integration log and the server action appears to complete (all the data returned from the REST calls is saved into the database).

Is this error always related to the REST API timeouts, or could this be due to a timeout happening elsewhere?

A project i am working on appears to be having a similar issue. keeps saying that outsystems.js timed out

Hi All

You can potentially set the Server Request Timeout under the module Defaults Section from the default 10 seconds to a more manageable value 

Further, you can change the timeout on the data fetch action on your screen (by default it has a value of "(Module Default Value)" in the Server Request Timeout field).

Hope this helps!


Hi i am having the same issue. May i ask the Server Request Timeout value 100 is this in second or millisecond ?

I have adjusted this value to a higher value but it did not resolves the issue.

I am trying to do a REST API to retrieved data from SAP

It works well in development but what come to quality server i keep getting time out, I check the error log but could not find anything.

Hope you can help thank you
