ERROR: Invalid configuration: endpoints.ps1 - after upgrade to 4.2.11

Hi all! After upgrading from 3.8.x to 4.2.11 we’re getting an error about HTTP versions. Can anyone help and tell what’s wrong and how to fix it?

Full error:

Status(StatusCode=“Internal”, Detail=“Error starting gRPC call. HttpRequestException: Requesting HTTP version 2.0 with version policy RequestVersionOrHigher while unable to establish HTTP/2 connection.”, DebugException=“System.Net.Http.HttpRequestException: Requesting HTTP version 2.0 with version policy RequestVersionOrHigher while unable to establish HTTP/2 connection.”)

Sometimes it even prevents the Endpoints page in GUI from loading.

Thank you!

Product: PowerShell Universal
Version: 4.2.11
as a service from MSI

We have a fix for this in 4.2.13. We disabled the proxy configuration in the gRPC client to avoid it. You can download the latest nightly to get the fix. We should have it out officially sometime later this week.

It seems that our proxy does not support HTTP/2. Is there a way to configure PSU or the underlying .NET to only use HTTP/1.1?
Thank you, L.
