Hello, we are using a proxyserver before our real webserver so that every request is transmitted through the proxy to our server. Normally that does not cause any problems.
But in egroupware at the calender function we can not create any new entry.
As we click at one hour a popup opens up, but instead of the input form we get:
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /extern/egroupware/index.php.
Reason: Error reading from remote server
Does someone have any idea if there could be any invalid headers send from egroupware??
Or if there is any kind of solution for this?
I don’t know whats with the other modules we are just using calender and admin.
