Sometimes, the site admits, but half of the Ajax methods did not work. How to fix it? Thanks

Sometimes appears next error:
Windows error
The pipe is being closed. (ERROR CODE: 232)

Hello.


Error from Zoo indicates the backend application did not respond in time after Zoo has started a backend worker. Since you find that internet connection is somehow involved it seems like your application is trying to download something from the internet, or simply hangs on it. Unfortunately, there is no any essential information in STDERR, so your application did not return any errors or even debug messages. It simply hangs and Zoo kills it after a timeout. Please try to troubleshoot your on that machine application without Zoo first, maybe you will stumble on the same error so you could find its cause.
