Unrecognized Ssl Message Plaintext Connection Spring Boot

Hi All

I am getting the following message when run my application

Caused by: javax.net.ssl.SSLException: Unrecognized SSL message,
plaintext connection?

Let me give a brief overview of my application.
This is a FTPS (NOT SFTP) client connecting to the FTP server on port
990. I am trying to connect to the server download the server
certificate and then load it dynamically in the trustmanager and then
do the normal FTP operations.
The application connects fine for downloading the ceritificate,
logging in and getting the initial working directory details. Thereon
any operation throws me this error.

CDIER0961E: The REST step is unable to invoke the REST service, cause=javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection? The scenario is as follows: I need to retrieve a token to be used in all following calls to the API. Expected Behavior SMTP TLS and SSL should send email using configured smtp details. Current Behavior Both TLS and SSL setting are failing for Spring javax mail. SMTP TLS is failing with 'Could not convert socket to TLS' I set the below g.

Any ideas are welcome.

Thanks in advance

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? java https

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.

But when I place the link in browser with https it works! And I need to perform a safe query. Any idea on how can I solve the problem? – rsy Mar 31 '14 at 14:06 5 @rsy When you 'placed the link .. with https' the browser would have changed to port 443 for you. You can do the same yourself. Indeed HttpURLConnection will automatically do it for you, if you don't specify a port at all. – EJP Jun 9 '14 at 23:54

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 javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection

props.put('mail.smtp.socketFactory.fallback', 'true'); // Should be true

up vote 5 down vote I got the same error message when I forgot to log in to the company firewall, before performing a POST request through a proxy.

this answer answered Apr 9 '13 at 12:01 Jay 198 3 17 I had to do the same although I was inside the company ! – MonoThreaded May 4 '16 at 14:19 up vote 0 down vote 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.

this answer answered Feb 3 '14 at 6:34 Soumyajit Swain 314 2 12 2 No, you got the error when accessing the HTTP port via HTTPS. Read the error message. You connected to a plaintext target. The situation you described wouldn't have caused an SSLException, as you wouldn't have been using SSL. – EJP Jul 2 '15 at 22:05 up vote 0 down vote 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.

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.

up vote 0 down vote As EJP said, it's a message shown because of a call to a non-https protocol. If you are sure it is HTTPS, check your bypass proxy settings, and in case add your webservice host url to the bypass proxy list

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.

this answer answered Mar 22 at 17:57 Faxon 9 2 up vote -1 down vote Another reason is maybe 'access denided', maybe you can't access to the URI and received blocking response page for internal network access. If you are not sure your application zone need firewall rule, you try to connect from terminal,command line. For GNU/Linux or Unix, you can try run like this command and see result is coming from blocking rule or really remote address: echo nc -v yazilimcity.net 443
