Can't connect Power Automate machine with Power Automate web.

Job ID: 34610668

Budget: $50 – $100 AUD

When creating flow via PWA web version, I get the following Desktop flows error:
"Test connection faled. Details: Correction failed: [Machine XXXX] There's er issue *'7th your credentials. Check your credentials or use different credentials to connect to the machine. Correlation id: XXXXXX"

I've taken the below actions and am now realising I'm not getting closer to fixing the issue...

Issue: Power Automate web wont connect to machine
I believe it's because the connection

***Actions I've tried***

1. Local user permissions checked (Computer Management)
I have the following allocated: (I added the three in the middle here…)
- Administrators
- Power Users
- Remote Desktop Users
- Remote management Users
- Users

2. NT Service\UIFlowService - checked that its allowed in the local group policies
(Local Computer Policy\Computer Configuration\Windows Settings\Security Settings\Local Policies\User Rights Assignment)
- Log on as a service - added
- Deny log on as a service - not present

3. Changing PA Machine runtime account (from default account, which is the NT Service\UIFlowService)
- To local account - didn't work.
- Using microsoft & 365 admin login details - didn't work

4. Checked PA version number - apparently there was newer available, but when I checked, the update that's been in stalled in August is definitely the latest.

5. Uninstalled PA Desktop locally - just in case it worked...

6. Re-installed it from online Power Automate - both PWA desktop & machine runtime


After testing the connections within the web PWA flow, I then gave up.
(not tried yet) Sign in using Web Account Manager (WAM)
- I'm joined with WAM on machine, so would imagine this to be redundant.

(haven't yet tried) Using a file named msalcache.bin3
