Issue:
url_response probe configuration via AC fails with multiple ppm related errors: "unable to retrieve remote data - check ppm.log"

Although errors are displayed when opening the url_response probe, you can press ok and still load the url_response config. When adding a profile we also see ppm error for failed callbacks. Also, the user agent section of the url_response probe via AC shows the following error: Unable to retrieve options (User Agent)

Increasing the ppm log level to 5 and logsize to 10000, we can see the following errors:

Environment:
- UIM v8.51 
- Robot version (where the probe is running) v7.80
- Windows 2012 R2 
- url_response probe version v4.43 
- ppm probe version v3.47 
 
Resolution:
1. Stop the url_response probe.

2. Open the url_response probe via Raw Configure.

3. Under the "setup" section manually add the following value "Nimbus/2.0" to the "User Agent" key.

4. Save the changes, reactivate the url_response probe and re-test.
