You’re offline. This is a read only version of the page.
I've created a desktop flow that worked fine for a few weeks, but now it only works the first time after I reboot my computer. After that, it always hangs at "Launch new Microsoft Edge" with the error:
Failed to assume control of Microsoft Edge (Communication with browser failed. Try reloading extension).
Microsoft.Flow.RPA.Desktop.Modules.SDK.ActionException: Failed to assume control of Microsoft Edge (Communication with browser failed.

If I reboot the computer, it will work again (once). Then it will stop working and always throw the error above. I've tried the following:
Any ideas on how I can fix this? I can't reboot my computer every time I want to run a flow.
When a user has a Work Edge and a Personal Edge profile, the browser extension can only be turned on in one profile otherwise there is conflict that stops PAD from accessing browser. Solution = turn off / uninstall the extension in the personal profile version of Edge.
I have been struggling with this and similar errors with the same underlying problem of PAD -> Edge control. Finally stumbled on the right Microsoft support engineer who figured it out.
Hope this helps.
THANK YOU,
I've been troubleshooting this all morning with chrome, tried doing all the reinstall suggestions and another machine, but restarting chrome a few times properly until i didn't see the restore message got it functioning again.
I have another computer with a windows 10 home edition on it. Here, I have to use Task Manager to kill Microsoft edge, then Start manually edge on the page I need, then Start the flow and it will eventually work till next day when I have to redo this again.
This had happened to me before, and as per the error message, i spent a lot of time debugging the extension. however, the actual issue was a change in selector/title when attaching browser. In my case, there was an additional profile in edge that started showing up which i had to wildcard.
Not sure if that's your issue but could be similar
I added a Retry 2 times with 5 seconds interval step to the Launch Browser task. It seems to be better; it may add a few seconds to the flow but since my flows run at night it is not an issue.
I'm facing similar issue, the page opens in a browser and flow continue to run few seconds then throws "Failed to assume control of Chrome (Communication with browser failed. Try reloading extension)". The flow that ran 3 weeks back is not working now. I tried simple flow opening a youtube channel url with both edge and chrome yet same error. Any update on this thread?
Hi @Mibsk ,
Thank you for adding to the conversation. Basically what you suggest is the workaround I described above. Instead of opening a new Edge instance, I attach to an existing tab, and it works. The problem is that this adds some manual steps to the flow, so I can't just click "Start" and forget it. Until Microsoft fixes this, I'll have to continue using Firefox.
Cheers!
Hi Jimbotron3000 🙂
I dont know if you have the same problem that i have been having, but ill give it a try anyways.
Are you using "Launch new Microsoft Edge" to hit a specific tab?
Or are you using it to open Edge from scratch?
Ive had the same problem as you when i try to hit a specific tab with "Launch new Microsoft Edge".
The error accourse when Edge is just a bit slow to get the tab open.
Even if i have retry on error on, it simply will not attache.
I made a wait for window with the specific tab title that i want to store the Edge instance for.
Then the problem has stopped for me.
But if you are having the problem with brand new opening of Edge then i have no idea how to help, since i have not experienced any issues with that.
@Jimbotron3000 Great news!! Awesome.
Cheers,
Ankesh
