Web Extension not connecting to RDM

Hello,

Did you set the same key in both the Web Browser's Remote Desktop Manager settings :

And in Remote Desktop Manager's File -> Options -> Browser Extensions like such :

Best Regards,

Hi,

Yes tried that but same issue, screenshots to confirm that we have tried setting the same key value between RDM and the web extension options for Edge,

Have also tried this in Chrome, but same results.

Thanks

Hello,

I will verify with the engineering department, keep you updated on that!

Best Regards,

Great, thanks!

Hello,

Could you also try to change the Port that DWL uses :

Best Regards,

Hi,

Tried changing the port to 19444 within both RDM and the web extension options but no joy.

Hi,

Could we please get some advise on how we can get the web plugin working again following the RDM update? A lot of our daily work flows and processes evolve around using this, so its vital we get this working again please.

Thanks in advance

Hello,

We are not quite sure why this would happen, do you work in a TS environment?

Hi,

No, we all use Windows 10/Windows 11 machines with RDM installed locally. As mentioned before, we updated RDM to the latest version this week and it is since then that this is not working. I have repeated this on several machines here and all having the same problem. We use both Edge (Chromium) and Chrome, both of which are kept up-to-date via GPO policies so we always run latest versions.

Are there any log files, or extra details that we can review which might give us an indication of why this isnt working? The fact that the extension doesnt seem to 'read' or connect to our local RDM clients would seem to the the main problem here I suspect?

Thanks

Hi,

Tried to go through this process however the Inspect Views section does not show a URL for us to select. This is the same on both Edge (Chromium) and Chrome,

Here is a screenshot from both Edge and Chrome, with Dev mode enabled,

Could this be the reason why the extension is not working, and if so why would this section of the extension properties not be shown on both browsers?

Thanks

Rich

Hello,

This is most likely due to an Policy, in this case it would be DeveloperToolsAvailability that doesn't see Inspect View.

https://chromeenterprise.google/policies/?policy=DeveloperToolsAvailability

We suppose that DWL was installed using an Enterprise Policy and so the result would currently be the following : Setting the policy to 0 (the default) means you can access the developer tools and the JavaScript console, but not in the context of extensions installed by enterprise policy.”

The workarounds are the following :

1. Change the Policy and set DeveloperToolsAvailability to "1"

2. Try with a profile where the Extension wasn't installed using the Enterprise's policy

3. Installing DWL on Opera if you do not have any policies related to Opera, from there, gather the logs.

Hi,

So managed to go through this, and have gotten further using a user account which doesn't have any policies applied for deploying the web extension.

The backgound.html page now lists under the Inspect Views for the extension, and can see the localhost entry is Red. It looks like this page is being blocked by our Sophos AV client due to this page being both uncategorised and also requiring Javascript,

Are you able to provide any background detail on how the web extension now works so I can further understand what we may need to tweak on the AV side of things to allow this work please?

Thanks

Rich

Good question, I will have to look into it.

Best Regards,

Hi,

So we have managed to resolve this issue by allowing the localhost:19443 website via our Sophos AV web protection client. In fact, we added 127.0.0.1:19433 to be allowed (as that will resolve localhost).

With this done, the web extension looks to be working again.

It would still be interesting to know any details on how this works from a backend perspective, to ensure we are allowing the correct site etc...

Thanks again

Rich
