Clients Booting into FOG are Met With "Attempting to check in......failed"

[FOGBreaker101]

We have had an issue where when clients are booting into FOG to run a scheduled task they fail a check in and just repeat the message.

This was on both the stable build and dev-branch. I updated to 1.6-working and everything is working normally. I’m curious what the issue was.

I have some error code as well regarding PHP:

[Tue Jan 13 13:24:55.033900 2026] [proxy_fcgi:error] [pid 2534002] [client xxx.xxx.xxx.xxx:53259] AH01071: Got error ‘PHP message: PHP Warning: Attempt to read property “dev” on null in /var/www/fog/lib/pages/dashboardpage.class.php on line 586; PHP message: PHP Warning: Attempt to read property “rx” on null in /var/www/fog/lib/pages/dashboardpage.class.php on line 588; PHP message: PHP Warning: Attempt to read property “tx” on null in /var/www/fog/lib/pages/dashboardpage.class.php on line 589’, referer: http://xxx.xxx.xxx.xxx/fog/management/index.php?node=home

The error log was just a repeat of the above.
I’m just curious what broke within FOG or PHP to cause this issue.

Thank you!

@FOGBreaker101 Please update and try again.

I am not 100% sure what the actual error is, but what I’m seeing from a DB standpoint there is a totally different issue occurring and that I could work around.

Can you try to update and try again? If you’re still having an issue and I can try to take a look.

@Tom-Elliott I had updated to 1.6-working after dropping the fog table in mysql and everyting is working correctly now. I posted this mainly as a “why did this happen” thing. I’m sorry for the confusion.

Before I went to 1.6 I had dropped the fog table from mysql and deleted .fogsettings from /opt/fog as well so it would do a new install without carrying any settings. Even doing an install after that it was still giving the error when trying to capture an image.
