While the installation of the providers is working locally totally fine it does not work on our CI system running at Hetzner Cloud:

```auto
Initializing provider plugins...
- Reusing previous version of hashicorp/aws from the dependency lock file
╷
│ Error: Failed to install provider
│ 
│ Error while installing hashicorp/aws v4.6.0: could not query provider
│ registry for registry.terraform.io/hashicorp/aws: failed to retrieve
│ authentication checksums for provider: 405 Method Not Allowed
╵

```

I have found [Failed to install provider and Failed to install provider · Issue #23481 · hashicorp/terraform-provider-aws · GitHub](https://github.com/hashicorp/terraform-provider-aws/issues/23481) which seems like access from Russia have been limited, but all systems are running in Germany and they are not connected to Russia at all.

What can we do? A curl request like `curl https://registry.terraform.io/v1/providers/hashicorp/aws/versions` is working totally fine. There are no connection limitations on our side.

Looks like this happens only on some IPs, I got another VM at Hetzner Cloud with a totally different IP address where everything works fine, but my CI Runner seems to be blocked somehow.
