Error Message: Received non-200 HTTP Code: 502

  • Hi,

    after Update to 2.4.3 i got sometimes (about 1-4x a Day) the Messsage:

    Exception calling XMLRPC method exec_php # Received non-200 HTTP Code: 502. Response body:<html>
    <head><title>502 Bad Gateway</title></head>
    <body bgcolor="white">
    <center><h1>502 Bad Gateway</h1></center>

    I found an old enty in the forum about a captive portal sync problem.
    At my installation there is a captive portal running with about 10 Zones.
    I'm using CARP and also HA-Sync for transfer config from master to slave-server.
    The Errormessage is only showed on the master-system.
    I couldn't find any impact but what does the message will say to me?

    A network problem is nearly impossible. The Servers have enough performance and network uplink.

    Does anybody have an idea where the problem came from?



  • Galactic Empire

    Are you running HA sync over a LAN setup for captive portal ?

    "It is recommended to set this to an interface other than LAN! A dedicated interface works the best."

  • Hi,

    thanks for reply.
    No, it's a dedicated interface and there is no captive portal in it.
    It's on a different Interface and also VLAN.
