Firewall seems to block big response to web server



  • Hello.
    I have a raspberry pi with some temperature sensors connected to it and a webserver to show it. http://familjenhuss.com/pitemp if anyone is intrested.
    My problem is that is I set a big interval to show in the chart, the page will never load, the chrome circle on the tab just keep spinning, but if I set the same interval when using the local IP, it works just fine.
    Is it some setting in the firewall regarding to big responses?

    No. It is probably the Pi having to crunch more data and taking some time to generate the graph (if it's not crashing in some fashion.)

    Ok, strange that it works when using the local IP then…

    That shouldn't make a difference.

    Where are you accessing it from when using http://familjenhuss.com/pitemp and it's failing?

    What is a "big interval" ??



  • I was on the same network, but now i am on a other network and it seems to work just fine.
    I choose a couple of days, from the 25 to today.
    Has it to do when accessing the the site with the external Url from within the same network?

    Edit:
    Ok, now I have tried to use the site from my internet sharing with my iPhone and the site works just fine!
    If I select from (från) 2016-07-18 00:00 and to (till) 2016-07-29 23:55 the page loads in a couple of seconds.

    But when Im on the same LAN, I dont get any response when i choose the same dates… The tab just keeps spinning...
    I have tried both WiFi and wired connection to the lan, same result.

    Something is not responding when Im using the external adress and are on the same LAN as the webserver, but I dont get a timeout, the tab keeps spinning.

    Further investigation seems that if I use the local IP, i get a POST in the access.log, but if i use the external url, I dont!
    Is it some firewall rule to handle that?
