I have an API management in internal mode. I have defined custom domain for all the APIM endpoints with self signed certificate. I can access Developer portal form VM connected to the same VNet as APIM. When I try to make a call from Developer Portal test console I get the following error:
The same call directly from browser on the same VM it works fine so it is something that happes in Developer portal.
I tried the following ways to enable CORS described here:
- enable CORS policy automatically
- enable CORS policy manually (for ALL APIs)
- CORS proxy option
None of them gave any visible result.
Is it possible to use Developer portal test console with APIm in internal mode?
If so, what should I make differently?

https://techcommunity.microsoft.com/t5/azure-paas-blog/azure-api-management-developer-portal-troubleshooting/ba-p/2790963As you are using a custom domain (and particularly if the domain for the dev portal is different to the management and data plane endpoints) it could be CORS but if it is that should be clear on a browser trace
I know you tried the advice here https://learn.microsoft.com/en-us/azure/api-management/enable-cors-developer-portal but please pay special attention to the notes around subscription key
