I have a java complied package to speak with the https server on net. Running the compilation gives the following exception:
I think this is due to the connection established with the client machine is not secure. Is there any way to configure the local machine or ports in order to connect to the remote https server?

I think this is due to the connection established with the client machine is not secure.
It is due to the fact that you are talking to an HTTP server, not an HTTPS server. Probably you didn’t use the correct port number for HTTPS.
You should have a local SMTP domain name that will contact the mail server and establishes a new connection as well you should change the SSL property in your programming below
I got the same error message when I forgot to log in to the company firewall, before performing a POST request through a proxy.
I got the same error. it was because I was accessing the https port using http.. The issue solved when I changed http to https.
I face the same issue from Java application built in Jdevelopr 11.1.1.7 IDE. I solved the issue by unchecking the use of proxy form Project properties.
You can find it in the following: Project Properties -> (from left panle )Run/Debug/Profile ->Click (edit) form the right panel -> Tool Setting from the left panel -> uncheck (Use Proxy) option.
Adding this as an answer as it might help someone later.
I had to force jvm to use the IPv4 stack to resolve the error. My application used to work within company network, but while connecting from home it gave the same exception. No proxy involved. Added the jvm argument -Djava.net.preferIPv4Stack=true and all the https requests were behaving normally.
If you are running local using spring i’d suggest use:
It works for me using unit test.
It worked for me now, I have change the setting of my google account as below:
Though I have enabled SSL and TSL while running program in this link of same post. I spend a lot of time but than I realized and found this link. And done 2 following steps and setting control in google. :
Disable the 2-step verification (password and OTP)
Enabling to allow to access less secure app(Allow less secure apps: ON.)
Now I am able to send mail using above program.
