At work, I am trying to deploy a java 8-based application on Tomcat 7 server.
The application should call some RESTful api based on another server (which is still ours). By reading some resources online I decided to use a HTTP request client library called Unirest.
I tried to call the api using Postman and everything works fine. I deployed my application on my LOCAL Tomcat 7 server and it runs smoothly without problems and Unirest does its job correctly.
When I deploy the application on the Tomcat 7 server, every Unirest call, leads to a connect timeout.
This is the stacktrace:
com.mashape.unirest.http.exceptions.UnirestException: org.apache.http.conn.ConnectTimeoutException: Connect to srv-erp2web.rold.corp:80 [srv-erp2web.rold.corp/192.168.5.100] failed: connect timed out

I haven't find any clue on the internet about how this can happen. The really strange thing is that Unirest calls correctly the api on my local Tomcat.
Here a snapshot of the code that I use to call the api:
public static String getAccessToken() {
logger.log(Level.FINE, "calling smartfabauth to get authentication token");
String accessToken = "";
try {
Unirest.setTimeouts(0, 0); // NO TIMEOUT
HttpResponse<JsonNode> response = Unirest.post(POST_TOKEN_ENDPOINT)
.header("content-type", "application/x-www-form-urlencoded")
.header("cache-control", "no-cache")
.body("grant_type=" + GRANT_TYPE + "&client_id=" + CLIENT_ID + "&client_secret=" + CLIENT_SECRET + "&scope=" + SCOPE)
.asJson();
accessToken = response.getBody().getObject().getString("access_token");
} catch (UnirestException | JSONException e) {
logger.log(Level.SEVERE, "[Exception] getAccessToken", e);
}
logger.log(Level.FINE, "authentication token obtained");
return accessToken;
}
Note that POST_TOKEN_ENDPOINT, GRANT_TYPE, CLIENT_ID, CLIENT_SECRET and SCOPE are some constants declared in class necessary to correctly call the api.
Any help would be apreciated.
Thanks in advance.
