Hello Deepak Ji,

The Application is Web portal (with https enabled)

So My understanding of telnet to the application IP, will give insight on 
connectivity part which is happening. That’s what I tried to verify 
connectivity.

What did you get back, when you used telnet? If you get something readable back on port 443 (which I assume, you are testing), it is probably a helpful error message from the server saying you should use an TLS client.

Use "openssl s_client -connect <servicename>:443" instead of telnet to test an TLS enabled service (As Dmitri said in another mail).

Plz provide more insight If you are suggesting to check any specific part for me

Harshit

If you have telnet listening to the port, then how would the application
listen on the same port?

Check if the port of servers are open (not the Jmeter machine)...

Hello Team,

While recording of the application Landing page from Windows Test machine
we are getting ‘connection reset’ error.

Kindly suggest what next could be tried in order to resolve the issue

Further have checked the below things as first steps:-
1 JMeter proxy certificate --> this is installed properly under trusted
root certificate
2 changing with port number --> instead of tried with port 8888 used ,
8181 .
3 Validated the listening port if already in use --> with netstat command
checked, neither of these are in us
4 Checked application access w/o configuring proxy in the browser -->
Able
to access the application landing page successfully
5 SSL version--> tried setting up the default protocol version in
jmeter.properties as TLS1.2 , this version verified from browsers
security
tab for my application
6 Firewall --> Test machines firewall checked , nothing is blocking there
& its in disable state
7 Antivirus---> Currently trend micro is antivirus used on my test
machine. Even after disabling the same, getting connection reset error
8 Browser proxy --> Currently there is no browser proxy enabled , so that
also rule out.
9 Manual ---> This anyway just a trial, where manual HTTP request created
using HHTP sampler & headers from developer tool-> network tab. But still
the same issue

Currently using below setup of Test machine
OS --> Windows 2016 servers standard
Jmeter --> 5.4.1 version
Java version installed --> 1.8.0

Regards,
Harshit
