Problem with comments: "error" listed and timing out

Hi!

Lately I seem to have problems with the comment section on my website. Whenever someone wants to leave a comment, they get an error message. Or the website keeps timing out or they get “connection was reset”. Some of the comments eventually came through, other comments never got published.

What’s the cause of this and how can I resolve it?

I use Jetpack for the comments and have senses lite as theme

My website is http://www.journalofnomads.com and here’s for example a post on which people get an error message: http://www.journalofnomads.com/miraculous-pools-pamukkale/

Any help would very much appreciated!!
