Hmm, EPROTOTYPE is a very strange error to get here. It suggests that our file descriptor is in the process of being torn down. This blog post appears to cover the case. I'll see if I can put together a reproducer and then apply a relevant workaround.

[saroar]

@Lukasa thanks for a quick reply
yes, I check that blog but don't understand anything :(
will install this
brew install reduce
and try to see if that error will be still there

[Lukasa]

You do not need to reduce this. This is a straightforward NIO bug, we don't need to generate a reproducer.

[Lukasa]

See apple/swift-nio#1706.

[saroar]

still have the same issue
I clean the project remove the driver after updateed the package
:( name issue

[Lukasa]

We have not shipped a new patch release. You would have to switch to getting NIO from master.

Where @Lukasa says master he actually means main

[saroar]

may i know when it will be shipped the new patch thanks

[saroar]

i after build from `main` unlimeted time never end request

[Lukasa]

It seems likely you're hitting an error somewhere that isn't being fed back to your Vapor application. It's hard to debug this without more information from you. Do you have logging enabled?

[saroar]

@Lukasa my vapor 4 https://github.com/AddaMeSPB/AddaAPIGateway
after 1 hour it still there sending request.......

[Lukasa]

We will need to see either logging or a network packet capture to make meaningful forward progress here. It seems like something is not being appropriately terminated, but we need more information to know exactly what.

[Lukasa]

Alternatively, you can use a debugger to intercept the behaviour of HTTP client and try to observe whether it is connecting, if it is connecting whether it is sending, and whether it is receiving any responses or errors.
