Recently I attempted to log into a nanobsd pfsense 2.2.3 firewall webGUI. Was not having any issues with the firewall other than not being able to access the webGUI.
Error:
503 – Service Not Available
Resolution:
- SSH into the box:
- Run option 16 ‘restart PHP-FPM’
On top of the webGUI not displaying I was noticing some delays when saving. The delay wasn’t browsing pages or ‘applying’ settings, strictly when I was saving settings it would take 15-40 seconds to load1)https://redmine.pfsense.org/issues/2507.
Run the following command to re-mount the filesystem2)https://doc.pfsense.org/index.php/Remount_embedded_filesystem_as_read-write:
To remount file systems as read-write, run:
|
1 |
/etc/rc.conf_mount_rw |
To mount as read-only again, run:
|
1 |
/etc/rc.conf_mount_ro |
To make the above settings stick (once in the web GUI) you can navigate to “Diagnostics>NanoBSD>Media Read/Write Status” and tick the ‘keep media mounted read/write at all times”3)https://www.reddit.com/r/PFSENSE/comments/4b1b5z/503_service_unavailable_found_a_fix/d15iobk.

Notes & References
Dude, I’ve been fighting this error for such a long time. After numerous reinstalls, the error would always pop back up. Thanks for the tip– it worked like a champ!
Glad I could help. I’ve amended the post to include the steps to take to keep the media mounted.
