Hi,
I am trying to send a grpc request using k6 and I am getting a timeout with this error:
GoError: context deadline exceeded: connection error: desc = “error reading server preface: http2: frame too large”
Has anyone encountered this issue?
Hi @aviklaiman !
Welcome to the community forums! 
It sounds like the connection issue 
Out of curiosity, does your service require authentification? Is it behind any proxy? Does the issue persist when you try to use another util like grpccurl?
Cheers!
@olegbespalov Hi,
Thanks - managed to solve it.

Hi! How did you solved your issue? We’re facing a similar situation.
do you mind sharing solution? i’m also facing the similar issue.
not sure if i got pass the issue, looks like the error “error reading server preface: http2: frame too large” is misleading, i tried to configure with TLS:
client.connect('<host>:443', { timeout: '5s' })
and then got pass this issue.
however, i’m facing:
unexpected HTTP status code received from server: 464 (); malformed header: missing HTTP content-type
not sure if this is server configuration issue? my but guess is the server doesn’t have application/grpc enabled
