CSRF Check

[spetrillo]

Hello all,

Ever since I upgraded to 25.7.11 I am getting the following when I login:

CSRF check failed. Your form session may have expired, or you may not have cookies enabled.

I have rebooted OPNsense but it does not fix this. What is this about?

Thanks,
Steve

Check the shortcut you're using to get to Opnsense.
It might have some trailing stuff that has state information in it that is no longer valid.
This bit me on the behind once too.

Hi Steve, I have a faint suspicion that you're having problems with the new Automatic Discovery feature in Interfaces -> Neighbors. This is unfortunately enabled by default on the latest update and known to cause excessive logging as well as high CPU usage. Log into the console and run

Code Select Expand

du -h / | sort -rh | headto see if your disk has run out of space. I'll bet that it has, and all taken up by /var/log/hostwatch.
Remove the logs and disabling the service will solve your issue.
