Request protocol 'HTTP/1.1' is not supported

Hello Community!

I have successfully installed EventStore database on Windows Server 2012 - and it works fine. But I try to connect to it using the GRPC client and I get the error “Request protocol ‘HTTP / 1.1’ is not supported.” Can I change something in the configuration or EventStore requires connection via HTTP/2 by design (which is not supported on Windows Server 2012) ?

Thank you for any feedback.

Hi there and sorry for the late response.

Could you provide more information like what the specific version of the database you used? Also, what parameters did you use to start the server?

I have already solved the problem. It did not work on Windows Server 2012 R1 - it works on R2.
