Hi, sorry you're having the issue. You mentioned you've tried to recreate the endpoint with this model and other custom models but still having the same issue. Have you tried serving one of the foundation models and seeing if that works or a really simple ml model? That way you'll narrow down the scope to whether something has changed in your environment for these custom models or not. A couple of things that could cause this would be some kind of permissions change, invalid token etc. Have you checked you still have access to all the model artifacts? If this isn't obvious you could try re-registering the model from scratch and try to serve it again. A lot of internal documentation recommends trying to check the error logs in the model serving UI, to see if there are any surfaced errors. But my guess is you can't get to this screen. I hope this helps to point you in the right direction.
