    Default 5.5.0 - Error 502 Error reading from remote server

    Hi,

    I am really sorry if this was there before but i googled for 5 hours and search those forums for another 2 and still no conclusion.

    I am running sugar 5.5.0 ... everything was alright but one day it stopped working with error

    Proxy Error

    The proxy server received an invalid response from an upstream server.
    The proxy server could not handle the request GET /crm/.

    Reason: Error reading from remote server

    I did nothing with server (Apache). I tried a lot of things event tried to reinstall but i cant finish install.

    I think it is not server problem because when i change something i config(db name) i get error or also when i try to reach some pag in that directory. I dont get this error.

    it is weird and i am really deperated. Thanks for any advices.

    The error is in the proxy server.

    First off are you actually using a proxy server to access Sugar. Most do not but make sure you need to.

    The other off hand suggestion is how are the proxy accessing the upstream server? Via IP or host name. If via IP, has the server (with Sugar) changed IP addresses for some reason. If host name, double check on the proxy server that the host is resolving correctly. (you should also do this on you desktop machine too!)

    Are you able to get to the other parts of the webserver? Double check to that the /crm directory still has the correct ownership rights. Could something have changed the ownershipp from the web server user name (usually apache:apache)?

    Hope this helps, Good Luck, Paris
