No connection established on gRPC with server-side TLS, self-signed certs

[krixlion]

Expected Behavior

A gRPC call goes through and either succeeds or a descriptive error is returned.

Actual Behavior

Error 14 No connection established is returned with no further messages or logs.

The only log from main.log that appeared after the request: [2023-08-13 16:43:46.269] [info] [gRPC] connecting to url=localhost:50055 with TLS

Reproduction Steps

1. Set up basic gRPC server with server-side TLS configured using my repo.
2. Create a new collection and a gRPC request.
3. Prefix the url with grpcs:// e.g grpcs://localhost:50055.
4. Add the CA cert in the collection settings.
5. Send the request.

Is there an existing issue for this?

• [X] I have searched the issue tracker for this problem.

Additional Information

I've encountered this issue when testing locally my own gRPC server written in Go.

Everything was working as expected until I configured server-side TLS using self-signed certificates. I can confirm the request is handled just fine when using a different client like grpcurl.

A minimal example including the certs I've used is here.
