Hello,

 

I need to create a secured MQTT connection between my broker and thingworx.
To do this I created certificate. The certificate is working fine when i use It with other program to test it.
However, after following this guide: https://www.ptc.com/en/support/article/CS0246701

I still have an error: OpenSSL Error[0]: error:14094438:SSL routines:ssl3_read_bytes:tlsv1 alert internal error

 

Does anyone have any idea on how to fix this ?

 Hi,

 

Found a mention of this error ("error:14094438:SSL routines:ssl3_read_bytes:tlsv1") in the article: https://www.ptc.com/en/support/article/cs345961 . And the solution: "Use JVM where this issue is solved and supported by ThingWorx".

Hi @AF_10328563.

 

How are trying to connect to the MQTT server?  For example, are you using an MQTT extension?  Are you using ThingWorx Flow?  This link from the Help Center may be helpful.

 

What version of ThingWorx are you running?

 

Regards.

Hi @AF_10328563.

 

Can you confirm which version of the JDK you're running?  What version of the MQTT extension is installed?

 

Regards.
