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.
I am getting an error and am trying to get an explanation as to its meaning. Anyone who can shed light on the meaning and the fix would be appreciated.
Firefox can’t establish a connection to the server at wss://myurl.com/socket.io/?EIO=4&transport=websocket&sid=66o3W59fgV4wklBbAAAO.
I am getting the error as 'ORA-03135: connection lost contact' from my C# code while making connection to oracle DB. The same job works just fine from our test server. But it failed with ORA-03135: connection lost contact error from prod server.
The C# code use ODAC to connect to oracle DB.
Appreciate your inputs.
Thank you
This error is most likely caused by a firewall blocking the connection request. Check for any firewalls in your network or on the database server and make sure your access rules are configured correctly.

ORA-03135: connection lost contact tips
What can I do to avoid the ORA-03135 error?
Answer: The oerr utility shows this for the ORA-03135 error:
ORA-03135: connection lost contact
Cause:
1) Server unexpectedly terminated or was forced to terminate.
2) Server timed out the connection.
Action:
1) Check if the server session was terminated.
2) Check if the timeout parameters are set properly in
sqlnet.ora.
The ORA-03135 error is common when connecting remotely when a firewall
terminates the connection.
One solution for the ORA-03135 error is to increase the value of the
sqlnet.ora expire_time parameter in the sqlnet.ora file or to check
for a expire parameter in a SQL*Plus profile.
To diagnose the ORA-03135 error, start by checking to see if the OS
PID still exists, using the "ps -ef | grep" syntax.
Check to see if there is a Network Address Translation (NAT) between
the client and server
In Windows, check to see if a Windows firewall is checking for your
local connections.
...
Also, setting the parameters sqlnet.inbound_connect_timeout and
inbound_connect_timeout_listenername to 0 can stop the ORA-03135
error.
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.
I'm trying to debug a machine that is located in China (very far from here) and the connection is very slow. The timeout of intellij remote debugger is short and therefore I'm getting Unable to open debugger port : java.net.ConnectException "Connection timed out: "
And I can't debug. Is it possible to increase the connection timeout? and how?
Try add -Djava.net.connectiontimeout=<seconds> to <IDEA_install_path>/bin/idea.vmoptions and restart IDEA.
But firstly ensure that port is opened and host is accessible, for example you can try to connect with telnet/another program.
