Jmeter is throwing Non HTTP response code - jmeter

I am getting the below error message from Jmeter v5.4.3 (after all the users ramped up) in the middle of the test:
Response code:Non HTTP response code: java.net.SocketException
Response message:Non HTTP response message: Operation timed out
I am getting it most of the times I run it. Any suggestions? Connect Timeout limits are already set in HTTP Request Default

It indicates that your server fails to respond within the bounds of the time frame JMeter waits for response
If it happens only under the load then there is nothing you can do from JMeter's side apart from setting/increasing connect and response timeouts in the HTTP Request Defaults. If you leave the timeouts empty it means "no timeout" so JMeter will wait for the response forever, but underlying JVM or OS can have its own connection timeouts defined.
You can also consider enabling debug logging for Java network stack by adding the next line to system.properties file (lives in "bin" folder of your JMeter instalallation)
javax.net.debug=all
and increasing JMeter logging verbosity for JMeter HTTP components by adding the next line to log4j2.xml file:
<Logger name="org.apache.http" level="debug" />
in general jmeter.log file is a good troubleshooting option

Getting Non HTTP response message: Connection reset message On Taurus Container

I am getting Non HTTP response message: Connection reset error
I have 2 calls.
POST HTTP request
GET HTTP request: I am extracting the location from the response headers of the first POST call request.
NO cookies or request headers to send for 2nd request.
When I run it from JMeter and Taurus YAML locally, everything works fine.
Running on JMeter on the Taurus container through, it runs fine.
Running YAML through the Taurus container, I am getting the above error: ** Non-HTTP response message: Connection reset**
Test Configuration:
execution:
concurrency: 1
ramp-up: 3s
hold-for: 30s
Not sure where the problem Is?
I tried other options like setting JMeter properties and others, for example:
hc.parameters.file: hc.parameters
http.connection.stalecheck$Boolean: true
https.sessioncontext.shared: true
https.default.protocol: TLSv1.2
https.socket.protocols: TLSv1 TLSv1.2
Checked the jmeter.log and bzt.log file for any errors. But none was found.
We cannot say anything meaningful without:
Knowing your test configuration (how many users, for how long, what is ramp-up, what it time to hold the load)
Seeing jmeter.log file (preferably with debug logging enabled for HTTP components)
Seeing bzt.log file and/or console output, again preferably with verbose switch
Seeing your container and container management engine health metrics (CPU, RAM, Network sockets, etc.)
In your case Taurus acts as a wrapper for JMeter test and it has its extra cost, it might be the case the container doesn't have sufficient resources to run both.

How to generate logs in jmeter when launching test from non-GUI

I am doing load test using 5 slaves machines. Upon reaching 50,000 users I am having connection reset errors and handshake errors. I have followed the steps mentioned in Jmeter report giving errors with distributed mode but errors don`t appear in result tree
and https://www.xtivia.com/fixing-jmeter-socket-errors/
When I use javax.net.debug=ssl, there is a long list appearing and it difficult to go through such a long list to find any error.
Can someone help with the different kinds of logs that can be generated and how to generate them as I am testing from non GUI mode. I have read many posts and so far I have not been successful to find the cause of these errors.
Is it related with sockets recycle? Is it from JMeter or the Client machines?
The errors are :
Non HTTP response code: javax.net.ssl.SSLException/Non HTTP response message: Couldn't kickstart handshaking
Non HTTP response code: javax.net.ssl.SSLException/Non HTTP response message: Connection reset
Non HTTP response code: javax.net.ssl.SSLException/Non HTTP response message: readHandshakeRecord
jmeter -n -t sso.jmx > stdout.txt 2>&1

Jmeter report giving errors with distributed mode but errors don`t appear in result tree

I am running my test in distributed mode from the GUI. I have some 20,000 users and two vitual machines have more than 4 VPCUs and 80 Gg memory. I can`t see any stress on any of the machines, neither the slaves or masters, nor the server under test and I could hardly see any error in the GUI. However, in the report, I am having the following errors:
Non HTTP response code: javax.net.ssl.SSLException/Non HTTP response
message: Couldn't kickstart handshaking
Non HTTP response code: javax.net.ssl.SSLException/Non HTTP response
message: readHandshakeRecord
Non HTTP response code: javax.net.ssl.SSLException/Non HTTP response
message: Connection reset
The errors are only 0.05%
Can anyone help me what these errors mean and how can I correct them.
You are not seeing the error in GUI because i.e. View Results Tree listener shows only 500 last results, it is controllable by view.results.tree.max_results JMeter Property and if you add the next line to user.properties file:
view.results.tree.max_results=0
next time you run JMeter you will see each and every request in the View Results Tree listener.
Be informed that GUI mode should be used for tests development and debugging, execution should happen in command-line non-GUI mode
For Couldn't kickstart handshaking and readHandshakeRecord - you can get some troubleshooting information by enabling debug logging for SSL, it can be done by adding the next line to system.properties file:
javax.net.debug=ssl
For Connection reset - see JMeterSocketClosed wiki article
If you have access to your application logs - check them for any suspicious entries

Kindly share if any attribute can be set in properties file or anywhere in jmeter to update the waiting time and maximum tries to get server response

Getting 'response code 504 - GATEWAY TIMEOUT' when run jmeter scripts in distributed mode (1 master, 2 slaves in aws - ec2 instances). Kindly share if any attribute/value can be set in properties file or anywhere in jmeter to update the waiting time and maximum tries to get server response.
Actually you are getting the response already so you don't need to change any properties as they will not have any effect. If you need to retry the request in case of receiving HTTP status code 504 follow the next steps:
Store response code into a JMeter Variable using Regular Expression Extractor like:
Once done you can put your HTTP Request under the While Controller and use the following condition: ${__javaScript("${code}" != "200",)}.
This way JMeter will retry executing the sampler until response code will not become 200.

What is the default response timeout in JMeter?

Can anyone help to know about default response time in JMeter if we do not set any timeout in 'HTTP request' sampler?
Thanks.
It defaults to 0 (no timeout)
The recommended way of setting the timeout is using GUI.
If for some reason it doesn't play for you you can use the following properties:
user.properties file:
httpclient.timeout
httpclient.parameters file:
http.socket.timeout$Integer
Both files live under JMeter's "bin" folder, JMeter restart is required to pick the properties up after the change.
