Proxy Problem in Talend Open Studio for ESB 7.2.1

[Basit]

Hi there,

I recently installed Talend Open Studio for ESB 7.2.1 on our Windows Server but I am experiencing problems with the proxy settings.

The traffic of this machine goes through a proxy and everything works fine. I can open websites in my browser. 

I built a job in Talend to call a REST Endpoint which results in a 'ConnectException: Connection timed out: connect'. The settings in Talend seem to be ok:

This is my error log:

It seems very weird because the exact same job works on other machines and even on this server everything has access to the internet except Talend.

Am I missing something? I would be glad if you could help me out.

Have the same problem with Talend Studio for Data Integration 7.2.1. I am trying to connect to https://jsonplaceholder.typicode.com/todos via the tRestClient but also results in a connection timeout.

Best regards

Hi Oliver,
please let me know if you are able to solve this problem. For me it looks like a bug in version 7.2.1 because the machine is definitely connected to the internet...

Hi All
It was a bug on v7.2.1
https://jira.talendforge.org/browse/TUP-24749
It has been fixed on v7.3.1, you can download the milestone version 7.3.1M5 and test if it works.

Hi,

the link you provided does not work for me, it shows only 

You can't view this issue

It may have been deleted or you don't have permission to view it.

I could navigate there to the sources and there I could find the links to open studio but it is linking to the main website and I guess there is the old version only available, correct? Actually I am using the Open Studio for Data Integration, but it also fixed there? I guess they use the same core branch? 

So, how can I download the v7.3.1

Thanks

[Basit]

Hi shong,

thank you for your reply. Unfortunately the error still exists with v7.3.1M5. I have talked again with our networkers and we will examine our proxy server again. I hope we can solve this issue soon.

I will keep you updated.

Best regards,

Basit

Hi Basit,

were you able to download the v7.3.1M5? Can you provide a link?

Thanks

[Basit]

Hi olja,

here you can download the different releases https://www.talend.com/products/application-integration/esb-manuals-release-notes/
Meanwhile milestone 6 is available for v7.3.1

I would be glad if you could report if you were able to solve your issue with the new version.

Best regards,

Basit

Hi @shong 

we have now troubleshooted our network settings and I even reinstalled Talend Open Studio (v7.3.1, release date February 26, 2020) but it still shows the same error. How can I be sure that this is not a bug in Talend Open Studio?

In addition to that I noticed that I am able to download and install third party modules in Talend (while having the proxy set in the settings). It seems that only the jobs don't recognise the proxy settings.

Regards, 

Basit
