 * Hi,
    I am using QuickLatex on my blog website, however since last week the formulas
   are not rendering (there is an error about connection timeout). I am guessing
   you might added my website’s ip to your blacklist as I am generating a lot of
   formulas. Let me know if that is correct? Many thanks, Dawid
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fconnection-error-27%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi,
    No, your website wasn’t blocked.
 * If you are generating many formulas – then it is normal to see “connection timeout”.
   
   Just re-load page few times until all formulas generated.

 * Thanks for quick reply. I am afraid that this is not the case, so I will try 
   to give more details.
    The error: _Cannot connect to QuickLaTeX server: cURL 
   error 28: Connection timed out after 10000 milliseconds_ appears when I try to
   preview/publish a new post. Interestingly, the error appears only for formulas
   that have not been not rendered before last week, i.e. they were added to the
   post after ~10th June (so let’s say $\theta$ was rendered before last week and
   it works correctly, but if I want to add something new like $\theta=999$ then
   the error appears). Moreover, if I create completely new post then the error 
   still appears.

 * Hi,
 * could you please reply to my previous post?
    The error persist even if you re-
   load the page several times.

 * Sorry for delay in reply.
 * I have no idea why this is happening on your website.
    Looks like your hosting
   provider has tightened up security settings or similar (e.g. disabled cURL module
   in PHP, etc.).
 * Have you done any changes to your PHP settings recently?

 * Don’t suppose you’re with Bluehost [@dawidkot](https://wordpress.org/support/users/dawidkot/)?
 * I started having this same problem recently despite it being fine before.

 * I attempted to contact them last week and did not get a useful response, only
   to try things like changing the theme. Please let me know if you hear anything
   useful.
