item.statusCode = 28? [Solved]

[Number8]

Hello,

Using async http, sometimes I get a timeout error. statusCode reports code 28 whilst statusText reports "Timeout was reached" (which is what is expected). I would expect code 408 instead of 28. Am I wrong?

From the sendsync() 6 docs: “If the statuscode is 100 or higher, it is a real HTTP status code returned from the server; if it is between 0 and 99, there was an error sending the request.”

Errors 0-99 match curl errors: 28 is “Operation timeout. The specified time-out period was reached according to the conditions.”

So error 28 notify you that something is wrong on the senders side.

Thanks waaren, this is very valuable information

Let me get back on this cURL error 28. I understand the error is triggered by the sender, that is dzVEnts itself, in other words, by Domoticz itself. I'm wondering what can I do about that. How can it be tackled? The code is pretty straightforward

Code: Select all

dz.openURL({
	url = ipxURL,
	callback = 'IPX800v3'
		   })

ipxURL is a private IP (LAN)
It is trigerred by the timer every minute. It fails a few times a day. What could be the root cause of the failure?
Current dz version is 2020.2 12485
Thank you

Just guessing but it could be a hickup in your LAN or router or a very busy system.

very busy system

You mean the gear on which Domoticz is installed?
Everything is wired 1Gb/s, so taking account what is expected on the LAN, I can't expect any bottleneck. Hardware is NUC Intel, i5 6260 with 8GB of memory
Does this error mean that the TCP/IP can't even leave the interface?

Does this error mean that the TCP/IP can't even leave the interface?

The messages tells you that curl (program or library) did not receive anything back within the default time. So no response from the target nor any error message.

All right, this is very clear, thanks again
