KRE licensing/proxy issues

Hi there,

I’m currently evaluating KSE and KRE with a trial online license for both to see whether it’s worth moving to v7.2.x from v6.1.4.x.

Our evaluation with KSE is going well, currently we haven’t really run into any issues. The only thing that we found is that we needed to to set up a proxy to access the license and the basic reporting plugin. Additionally we needed to use the proxy excludes option to add some domains for the applications under test.

When moving to evaluate KRE on the same machine, I get the following error/info messages

i’m assuming the KRE is not picking up the proxy information from


Is that correct?

We need the KRE running in our evaluation before we can get the GO to buy the licenses. Could you please let me know what I’m doing wrong, or what I need to do to get the KRE working?

Thanks a lot for your support.

Hi @autom

KRE does not use the same proxy information as KSE. Instead, it uses proxy information passed into the command line. Please refer to this documentation:

And let me know if passing the correct information helps. It’s also worth noting that you should avoid copying/pasting from another text editor, as it may drag along invisible illegal characters. It’s best to type in the proxy parameters by hand.

Excellent, thank you this works.

At the end of the execution, I now get the following exception, so KRE doesn’t seem to be finalizing the execution cleanly.

Have you seen this problem before? Must it be avoided? If so, how?

Thank you!

Hi @autom

It looks like the email part is wrong. Please go to Project > Settings > Email to see if you enabled the option and any field is missing.

How do the settings in KSE have an impact on tests executed using the KRE? I thought now they were separate executables?

I’m not using the email functionality at all and is all set exactly as it came with the product. Can I enforce the KRE to ignore email, or not to check for any settings?

Hi @autom,

The email setting affects the project, which will be picked up by both KSE and RE. It won’t affect much, just annoying log messages. But if you haven’t configured any email setting then you shouldn’t see this. Can you provide the screenshot of the email setting ?

Hi @ThanhTo,

OK, there was something in the recipient field, …but I never added it, …it wasn’t an email address, it was something else. I forget now as I’ve already deleted it.

But once I deleted it, correct, the exception no longer comes when executing from the cmd line using the KRE. Thank you for your help and pointing me in the right direction, I really appreciate it! :slight_smile:
