Trados Studio 2026 - Unable to connect to Azure OpenAI

Hi,

I just downloaded Trados Studio 2026 and I can't connect to my Azure OpenAI endpoint. I was able to connect with OpenAI Provider in 2024 with connections setup a long time ago, but now when I add connections it doesn't work either.

I'm not sure what to enter in the Endpoint vs the Model fields. Here is what it looks like : 
Add Model Connection window showing Connection tab with fields for Name, Provider, Endpoint, Models path, Auth, and API Key.
Add Model Connection window showing Model tab with fields for Model, Reasoning model checkbox, Max Tokens, Reasoning Effort, and Verbosity.
Error message window with text: Connection Failed. Code: 404. Message: Service request failed. Status: 404 (Resource Not Found).

I tried moving around the "deployments/gpt4.1" part in both fields, but it still fails.

On the Foundry side however, it seems that requests sent from Studio leave out the middle part (top is how it should looks like in 2026 and bottom is a request from 2026):

Screenshot showing two URLs with highlighted text, one containing 'aifndry-dev-zeus-produits-traduction' and the other without it, under the ClientProtocol column.

Is the solution to be found in Trados' settings or in Foundry?

Thanks,

Charles
