# Which Problems Are Solved
The current maintained gRPC server in combination with a REST (grpc)
gateway is getting harder and harder to maintain. Additionally, there
have been and still are issues with supporting / displaying `oneOf`s
correctly.
We therefore decided to exchange the server implementation to
connectRPC, which apart from supporting connect as protocol, also also
"standard" gRCP clients as well as HTTP/1.1 / rest like clients, e.g.
curl directly call the server without any additional gateway.
# How the Problems Are Solved
- All v2 services are moved to connectRPC implementation. (v1 services
are still served as pure grpc servers)
- All gRPC server interceptors were migrated / copied to a corresponding
connectRPC interceptor.
- API.ListGrpcServices and API. ListGrpcMethods were changed to include
the connect services and endpoints.
- gRPC server reflection was changed to a `StaticReflector` using the
`ListGrpcServices` list.
- The `grpc.Server` interfaces was split into different combinations to
be able to handle the different cases (grpc server and prefixed gateway,
connect server with grpc gateway, connect server only, ...)
- Docs of services serving connectRPC only with no additional gateway
(instance, webkey, project, app, org v2 beta) are changed to expose that
- since the plugin is not yet available on buf, we download it using
`postinstall` hook of the docs
# Additional Changes
- WebKey service is added as v2 service (in addition to the current
v2beta)

# Which Problems Are Solved
Adds `failed attempts` field to the grpc response when a user enters
wrong password when logging in
FYI:
this only covers the senario above; other senarios where this is not
applied are:
SetPasswordWithVerifyCode
setPassword
ChangPassword
setPasswordWithPermission
# How the Problems Are Solved
Created new grpc message `CredentialsCheckError` -
`proto/zitadel/message.proto` to include `failed_attempts` field.
Had to create a new package -
`github.com/zitadel/zitadel/internal/command/errors` to resolve cycle
dependency between `github.com/zitadel/zitadel/internal/command` and
`github.com/zitadel/zitadel/internal/command`.
# Additional Changes
- none
# Additional Context
- Closes https://github.com/zitadel/zitadel/issues/9198
