  Try clearing your browser cache or try another browser.

  It may just take a while to update fully, so I would leave it for a while before considering a recovery.

  Can you ping it or SSH into it ?

  Hi Martin,

  Glad to see you again ~ this is the status :

  Try clearing your browser cache or try another browser. => Done, both Chrome/Opera (brand-new installed at PC) failed the connection too.

  Before issue happened, the firmware has been updated to 1.570 and worked fine one or two days.

  Ping it. => Got responses as can be seen below.

  

  SSH into it. => Serial-port connection to BBG ? I'm noob with EVB/Linux and never dd things like that before. . well i have to learn this a while and prepare for the worst.

  thanks a lot, anyway.

  Hi Jimmy,

  That's odd.

  What happens if you ask for it's status using the webrowser as normal with /status after the port number, assuming you are using 8073

  192.168.1.151:8073/status

  Unfortunately that's about my limit with Linux too, but it looks like either the webserver part has stopped or the port number has changed.

  Have you tried a power cycle ?

  Otherwise it's over to more qualified folks to comment.

  Regards,

  Martin

  Isn't there an ssh available from the command line in Windows? Failing that, try the PuTTY application. So first try ssh root@192.168.1.151 and use the Kiwi serial number as the password (written on the top of the Kiwi circuit board in the white box).

  Once connected try these commands:

  cdp

  ps ax | gr kiwid

  msl

  Email the resulting messages to support@kiwisdr.com

  Hi, jks

  Putty access for log was done.

  Mail sent and thank for your help in advance.

  Hi Jimmy,

  Thanks for your complete and detailed email. It really helps me when people send me the info I ask for. You were correct. There was indeed an error parsing the configuration file kiwi.json We've seen this happen a few times in the past. It is not clear why this happens. Possibly a power failure at a bad time (when the file was being written).

  You should be able to get the Kiwi going again by using these commands after an ssh connection:

  cdp

  cp unix_env/kiwi.config/dist.kiwi.json ../kiwi.config/kiwi.json

  Note the ".." (two dots) above. When the Kiwi server next restarts (in a minute or so) it should begin running normally. Your customizations will be lost, but it is much better than having to start over re-flashing using the sd card.

  If you happen to have a backup made using the admin page, backup tab function, then a more recent kiwi.json file with some of your customizations can be recovered. Let me know we need to do this.

  Hi jks,

  These command lines are really powerful and work well ! Thanks a lot.

  

  
  

  As a record shown below is the ssh msg I see in this issue, and hope it can help someone too in the future.

  

  
  

  Enjoy KiwiSDR !
