Error Register MX

  • 1.  Error Register MX

    Posted 09-01-2020 12:05
    Hi community, 

    My client has an MX and a GW in version 14.2, last week we updated these devices, before they were in version 13.5.0_20, the GW has 4 mssql agents and 3 as400
    agents registered.
    Since Friday the GW presented a disconnection alarm in the GUI, we tried to enter the gw through SSH but it did not allow us to connect, therefore, we connected through the console port and validated the state of the gw and it is ok , it appears registered and running but in the gui it appears disconnected, we also try the telnet test from the GW to the MX through port 8083 and it is ok, then we try to force the GW registration to see if it was connected but when running the command it responds with the following error:


    Additionally, we restart the MX but I do not change anything, also the GW and it continues up but continues to appear disconnected.

    Can anybody help me?
    Thanks

    @Ivan Velasquez,  Does the GW exist in a cluster?

    Hi Ivan,

    Hope you upgraded gateway first to new version. Did you try de registering it and then register it.

    Thanks

    H Ivan,

    How many GWs are there? If there is a single GW, Maybe the IP address mentioned could be taken by another device. But if there are multiple GWs and just that one failed to connect to MX, that situation invalidates my theory.

    I faced issue like this and it's very hard to detect. When IP is taken by multiple devices, each device takes the IP irregularly and this can trick you easily. Also, this can explain SSH login fail. You can try to change MX's management IP address and then try to reregister the GW.

    I'm aware that it's a very unlikely situation but believe me, it's worth to check it :)

    Regards.

    I  connected directly in the interface eth0 with my PC and I configure my IP in the same network segment that my GW even so I can't connect with my GW with SSH only the console port does work.
    Do you know if I can change the admin and LAN interface for other ?

    For example

    Currently eth0 is management interface and eth1is LAN interfac

    I want to change for eht2 my management interface and for eth3 my LAN interface.

    Is it possible?

    Thanks for your help.
