Bizagi Modeler - msi install shows "No Internet connection" upon clicking on "Sign In" and version

I've extracted the msi using BizagiModelerSetup_4.0.0014.exe -a which spat out Bizagi Modeler.msi

and as we are on the enterprise plan, the documentation states that I need to install using:

"Bizagi Modeler.msi" /qn companyname=[Company_name]

(not sure if the URL needs to be prefixed with https:// or not but I've tried both ways)

"Bizagi Modeler.msi" /qn companyname=https://model-pic.bizagi.com
"Bizagi Modeler.msi" /qn companyname=model-pic.bizagi.com

At this point everything appears to be working OK apart from the "Sign In" throwing:

No Internet connection
Bizagi Modeler is trying to connect to the cloud but it seems there is no Internet connection.
Verify the following:
Make sure your device is properly connected to the Internet.
Review the firewall/proxy settings, they could be blocking the connection to Bizagi services.
Contact your network administrator to search for network issues.
The site could be temporarily unavailable, try again in a few minutes.

Error also attached (Bizagi Sign In Error.png)

If I install with "Bizagi Modeler.msi" /qn the modeler doesn't even open:

Running BizagiModelerSetup_4.0.0014.exe and manually feeding the company name by ticking "Setup Enterprise subscription for Modeler Service" works as expected i.e. I can sign in without issues (Bizagi Sign In OK.png) - this most likely rules out any firewall/network related setup that's missing at my end.

Lastly, the application is displaying the wrong version i.e. Help > About shows 4.0.0.014 (Bizagi Version.png)

but Add/Remove Programs pull the version from Registry as 4.0.0014 (Bizagi Version Add Remove.png)

Can someone please clary the version situation for me as well as the sign in error above?

Many thanks,

Adrian
