Can't access Mango ui page - need help


  • Hi,

    Need help. I can't load the Mango ui server page at MangoES:8080 after leaving it overnight. I still can access it via ssh though.

    Browser messages: Chrome-"This site can't be reached", Firefox-"Unable to connect"

    I'm on ES-V3-XU4.

    Note: I installed Mango free version on a PC some time ago and so far it's still working great.

    Thanks.
    Budi


  • On the MangoES Mango is running on port 80, unless you changed it you don't put in any port after your IP. Try putting in just the ip address of the MangoES into your browser.


  • It seems that the problem still persists, I mean I can't access the mango ui and dashboard after leaving it overnight, my browser gives me message "the site can't be reached, connection refused."

    But I still can ssh into the mangoES and run it again using ./ma.sh start to make it work again. Any issue with this, because on PC there is no problem. Thanks.


  • Hi Budi,

    Can you power cycle the device, then check the end of the /opt/mango/log/ma.log file for what has occurred? What user are you ssh'ing to and running Mango under?


  • Hi,

    I checked the log. I think the 'FATAL' logs could be the reason:

  • How to solve the problem? Thanks.


  • Ok somehow you have the brewers dashboard module installed. Please remove it by clicking the trash can icon on the Modules page next to it and then click the "Restart This Instance" button and the module will be removed. I'm not sure how you got this module installed but it should never been there as you need a special license for it.


  • Great. It's ok now. Thanks.
