MTD VAT Error for Windows 2012 (Opera Server and RDS)

tcyprys

Got a strange one and have been following other posts regarding MTD VAT and authorising - so I am just wondering if someone has come across this specific one.

Client dials into a Win 2012 Remote Desktop; Opera 3 server is also a Win 2012 server.

When they click on MTD VAT Centre for a particular company, it asks to authorise. When you can click through the first two HMRC  pages to allow the software to interact with HMRC, the 3rd screen is this:

I cannot get around this at all. 

Interestingly, I had another site that had RDS win 2012 with the same issue. The server was win 2019 and that allowed the user to Authorise and has confirmed that even on the win 2012 it is fine now. So it seems it is a problem with just the win 2012 (but might be just a coincidence)...tried all the usual stuff re authorising except I cannot get the redirection tick box to re-appear; not sure if this is the same thing though... let me know.

Hoping someone has seen this before.

Cheers

We have seen this problem on two servers recently. Both running very old server OS, I think it was 2008 and a windows 7 PC. 

Couldn't find a way around it other than to run the authorisation process from a newer OS. I think it's a compatibility issue and the authorisation process no longer works on the older OS. Not sure of the exact cause though.
