Hi,  
on my ubuntu test machine, we are running node-red in a vm using win11. Later on we want to transfer the vm to another machine.  
Actually we can't even install node-red. I set the npm proxy for http and https.  
Getting following error:  
reason: write EPROTO DC130000:error:0A00010B:SSL routines:ssl3\_get\_record:wrong version number:c:\ws\deps\openssl\openssl\ssl\record\ssl3\_record.c:355:

Is this a problem of proxy or ssl3??  
Thx

What command are you running that gives that error?  
In fact please show us the command and the full output from that command.

Also show us how you set the npm proxy (using http).

Got it...  
set the https-proxy=http **s** ://  
changed it to https-proxy=http://  
now it works.

Is your Ubuntu base image up-to-date? Because that looks like a TLS configuration issue to me (though I'm certainly not 100% certain).
