Running Instruments from the command line I started getting this:
instruments[2387:30342] Connection peer refused channel request for "com.apple.instruments.server.services.wireless"; channel canceled <DTXChannel: 0x7fa7116b7a10>
Any idea what the problem is and how to fix?
I'm also doing some research to find out the root cause of the problem. However, making sure Instruments is not running and/or restarting the device solved the issue.

How can I fix this message? A message appears when downloading
Problem Description
When I was using Node.js and generated the file package.jons, I found there's a warning at the start:
Problems loading reference 'https://json.schemastore.org/package': Unable to load schema from 'https://json.schemastore.org/package': Failed to establish a socket connection to proxies: ["SOCKS5 127.0.0.1:1090","SOCKS 127.0.0.1:1090"].
Possible Reason
Then I searched the error message Failed to establish a socket connection to proxies, and found maybe it's a wsl2 proxy problem according to this github reply.
For more precise reason, I searched the VSCode proxy document metioned by the reply, and found maybe it's caused by wrong proxy setting.
Ways to try
According to the VSCode document, I want to try the setting of "Manual proxy address". But I encountered two problems:
I don't know how to run the command line mentioned in the VSCode document: --proxy-server=<scheme>=<uri>[:<port>][;...] | <uri>[:<port>] | "direct://".
I don't know where to find the file /etc/resolv.conf mentioned in the github reply to get the wsl server ip.
When I switch my VPN into global mode and restart VSCode, the warning disappear.
Am trying to connect vertica from DBeaver, but am getting below connection error. Initially it was working fine, but suddenly its throwing connection error.
Error Message:
[Vertica][VJDBC](100071) GSS authentication failed due to problems establishing a TGT with JAAS using configuration verticajdbc; reason: Message stream modified (41).
Message stream modified (41)
Message stream modified (41)
I am not able to establish the connection now. Can anyone please help me on it.
The main issue I see with vertica users struggling to connect relate to the drivers used or where the host has changed. Have you updated vertica recently or has there been a change to the host name are just a couple of things you should check.
Sorry I cant be more specific its hard to troubleshoot when I dont have all the information.
Thanks
I'm using Google's simplehttp2server go-lang program to run some tests and have encountered a recurring error. Upon executing the TLS handshake I receive the following error:
2019/12/12 12:42:55 http: TLS handshake error from 127.0.0.1:36202: read tcp 127.0.0.1:5000->127.0.0.1:36202: use of closed network connection
I have updated my go version to 1.13.5 from 1.12.9 and tried two browsers (brave + chrome) plus curl and receive the same error code each time. It happens over HTTP/2 and HTTP/1.1. I have seem other answers from across the web but am still running into this error (ex1, ex2, ex3, ex4).
Very much appreciate any feedback, advice, or admonishment. Anything to help the migraine this problem is giving me!

This error happens when you have two websockets connected to a singular address using the same port from the same machine. One of the websockets will be able to connect fine but the other wont be able to make the connection.
I was making the same mistake and when I removed the duplicate connection the error resolved.
I am getting socket exception for broken pipe in my client side.

It seems that the upgradation of httpclient jar is causing issue.
Issue is not coming with httpclient-4.3.2
Exception is coming in every 2 minutes. Issue is intermittent at times.
after , send expect:100-continue ,conn.flush is throwing exception
client and server are Linux machine
client uses http jar to make request to server REST.
Please help me in debugging the issue
can httpjar cause such issue?
The persistent connections that are kept alive by the connection manager become stale. That is, the target server shuts down the connection on its end without HttpClient being able to react to that event, while the connection is being idle, thus rendering the connection half-closed or 'stale'
This is a general limitation of the blocking I/O in Java. There is simply no way of finding out whether or not the opposite endpoint has closed connection other than by attempting to read from the socket.
If a stale connection is used to transmit a request message the request execution usually fails in the write operation with SocketException and gets automatically retried.
Apache HttpClient works this problem around by employing the so stale connection check which is essentially a very brief read operation. However, the check can and often is disabled. In fact it is often advisable to have it disabled due to extra latency the check introduces.
The handling of stale connections was changed in version 4.4. Previously, the code would check every connection by default before re-using it. The code now only checks the connection if the elapsed time since the last use of the connection exceeds the timeout that has been set. The default timeout is set to 2000ms
