I use macro volt template, but I can't open the page from yesterday. On my brower it's showing :

This site can’t be reached

The connection was reset. Try: Reloading the page Checking the connection Checking the proxy and the firewall ERR_CONNECTION_RESET

....

If I delete endmacro block on view template, the page is available.

So, May I know what happend ? how to fix it ?

Did you update phalcon or something ?

Did you update phalcon or something ? not yet. I am using windows10. And what I did before that is just update IIS service on my computer (I already disable it not)

Hm, could it possibly delete phalcon extension or change php version or even change php handlers or something ? I don't know anything about it. Just a guess.

Try to get more info about your error, enable detailed reporting first: https://forums.iis.net/t/1176836.aspx

IIS, Windows10. You applied patch by Microsoft. -_-

Have you tried your app on a real setup? I'm sure it will work.
