Title: error establishing a secure connection Last modified: October 19, 2016 --- # error establishing a secure connection * Resolved [tmmslynn](https://wordpress.org/support/users/tmmslynn/) * (@tmmslynn) * [9 years, 7 months ago](https://wordpress.org/support/topic/error-establishing-a-secure-connection/) * Hi everyone, * I am using Postie. To date I have not had any problems with it. I run the blog for my school and we use this for teachers to post to their pages. Today I had a few teachers say they sent them email but the post is not up yet. When I go to process emails i get this error message “error establishing a secure connection” * What might this mean? and how can I fix it?
