Hello,

I'm having a issue with nagstamon.
I tried deleted everything a installing it again.

I launch the debug mod on it so i have something to show you the error.

json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

Hello,

Please have a look at this bug #1002

It it doesn’t solve your problem :
Can you try to enable the debug mode (Setting > Servers) and post the output ?

🧨Don't forget to remove sensitive information, like hostname of Centreon, credentials, ....
