Client network socket disconnected before secure TLS connection was established

Hi Community,

So, After I updated the VSCode recently, this error is getting thrown most of the time either when i try to retrieve 'the source from org' for a single apex class or when i try to 'Retrieve Source in Manifest from Org' from package.xml file.

I think it might get fixed after reinstallation. But that can cost me some time, setting up org, installing extensions again and all.

How can fix this issue ? Help ! 
If you know the solution, please share it.

Hi Vishnu,

I am also facing the same issue rightnow.(ERROR:  Error: Client network socket disconnected before secure TLS connection was established)I have tried all these things mentioned above and nothing is working for me.

I tried using SFDX source commands from terminal and it works for me.
So, until you find out the permanant solution/root cause, you can try using sfdx commands.
(https://developer.salesforce.com/docs/atlas.en-us.sfdx_cli_reference.meta/sfdx_cli_reference/cli_reference_force_source.htm#cli_reference_force_source)
e.g.
sfdx force:source:retrieve -m ApexClass:YourClassName(to retreive specific class from org)
sfdx force:source:retrieve -x path/to/package.xml(To retrieve all metadata components listed in a manifest)
sfdx force:source:deploy -m ApexClass:YourClassName(To deploy a specific Apex class)

Please let me know if this works for you.

Thanks,
Herin Acharya

Hi Vishnu,

Try to update Salesforce CLI, command: sfdx update.

Check below steps mentioned below.

https://developer.salesforce.com/docs/atlas.en-us.sfdx_dev.meta/sfdx_dev/sfdx_dev_troubleshoot_cancel_auth.htm

If above doesn't work then you would need to re-install again.

Hope above information was helpful.

Thank you for the reply Vinay,

I did both ways : Update SFDX and Killing the process(which i could find any named ''Node" in windows).

Think i have to re-install it.

Sorry to hear that it didn't work.  Unfortunately as you are aware you would need to re-install and that should fix the issue.

Thanks,

Yes you can see some guidance about this issue here because when I faced client network socket I took guide from here (https://electricdogfencesguide.com/best-wireless-dog-fence/)

I am also getting this error.
As a workaround , you can go to the org rowser ie the cloud symbol on the left of VSCode and retrieve each component to local
That works for me

Do you use VPN? Probably got trouble with proxy. 

I encounterd same error as you. Here is what i did: 

1. Update the lastest version of Salesforce CLI 

2. Change setting in VSCode: File > Preference > Application > Proxy 

  • Proxy Authorization > Edit in settings.json : write the proxy you are using here "http.proxy":"http://username:password@proxyserver:proxyport" , Ctrl S to save the json file 
  • Return to VS Code proxy setting, uncheck " Proxy Strict SSL "
  • Restart VSCode and tada, work like a charm

Hi Kunal and Hoangng,

Thanks a lot for sharing.

Actually, we started using a different sandbox and discontinued the older one - where this error was observed.
In the new sandbox, it is working fine without any errors mentioned above.
It might be possible that the old sandbox is having some problem.

Anyways, thank you for sharing as this could help someone in the future.

Have a great day !
