Duckstation - Cheevos Error: Get Patches Failed: Empty Response

[Rictro]

I'm having an issue where any PS1 game opened in Duckstation through Launchbox gives me the following error - "Cheevos Error: Get Patches Failed: Empty Response"

If I run the same game standalone in Duckstation it loads achievements with no issues.

• I have disconnected and reconnected the Retroachievements login in both Duckstation and Launchbox settings. Generating new tokens each time. Username/Password is correct. It shows a successful login. 
• If I disconnect Launchbox from Retroachievements I still get the same issue.
• I'm running the latest Launchbox and Duckstation.
• Launchbox has no issues with any other emulator.

Please could someone help on what else could be causing this?

I'm hoping this is something really simple, I'm happy to look stupid here.
