Pega Robotics. RDA - Failed to connect to MessagingHost within the given timeframe
When running RPA Local Project; the projects starts up and launches Chrome (which is what it is supposed to do), but then after 20 seconds I see:
Failed to connect to MessagingHost within the given timeframe of 20 seconds. Continue waiting?
Clicking on 'Yes' (several times) just results in seeing this message repeatedly.
The Chrome browser never changes from the initial log-in screen (the project should go on after ~10 seconds) to automatically login and then perform some other automations.
How can I diagnose this?

Generally this means that the Chrome extension is either not installed or not enabled. Navigate to the URL below.
chrome://extensions/
You should see an entry for "Pega Robotic Automation for Browsers". It should be enabled. If not, you'll need to install it. This can be done from the initial installer by selecting the option to install the extension, or if you have already elected not to install it but now need it, you can install it from the command line. OpenSpan.WebExtensionInstaller.exe is located in the installation directory.
OpenSpan.WebExtensionInstaller.exe Chrome -i

Hi, I have similar problem but on Edge and the Pega Extension to Edge browser is enabled. I encounter this when I interrogate an Edge browser.
Please advise.
Thank you.

@NickM591 I would suspect that your extension is not properly registered either. Did you install the Edge extension with Studio? Edge also has the option of running sites in Compatibility-mode. If you have an older version on 19.1 (CM support was added in 19.1.86; the latest version currently available), then you would not be able to interrogate any sites using CM in Edge. You can tell that by the IE icon in the address bar. If that is the case, you'll need to use 19.1.86 at least. You can install and register the extension in Edge with the following command;
OpenSpan.WebExtensionInstaller.exe Edge -i

Hi Thomas, I can proceed with the Universal web application as am getting the option "Create Global web page" check box in the interrogation form. I have reinstalled Robot studio with all default settings and selected Browser extension and selected the repaired option during the 2nd installation.
But am not able to proceed with the windows application as the interrogation form is closing as soon as the windows application is opening. I have tried with Calculator and i have observed, the moment the calculator is opening the interrogation form is closing. So there is no way to interrogate a windows application.
Am using, Windows 11 and Robot Studio 19.1 - latest version installed 21/09/2022.
Please let me know your inputs.
Note: In Robot studio, 2017 version these were working seamlessly. :-)

Found the below link,
https://support.pega.com/support-doc/microsoft-edge-update-113-prevents-you-automating-edge-pega-rpa
Edge version 113.0.1774.35 was not working using Pega Robot Studio
Upgrading to next version or rolling back to previous version solves the issue
Thank You
