Issue/Introduction

Trying to monitor a URL using url_response probe 

Keep getting an error "35 SSL connect error"on Test connection

On trying to open the same url using chrome or curl, it populates with no issues

 

Environment

Release : 20.3.x/ 20.4.x

Component :url_response v4.50

Resolution

Can see below error in url_response logs

Curl output for url 

Manually running curl on the url  shows the server / client negotiating for TLS 1.3 

In this use case changing url to provide TLS 1.2 on the server instead of TLS 1.3 solves the above error as currently url_response supports TLS1.2 

 

Support for TLS 1.3 for url_response probe is taken as a enhancement request
