Report Page Fails with 504 Gateway Timeout

  • Hello OMV Community,


    I am having a recurring issue with the "Diagnostics → Report" page on my OMV installation. Every time I try to load it, it tries to load for several minutes before ultimately following with this error: "Http failure response for http://192.168.1.2/rpc.php: 504 Gateway Time-out"


    Has anyone else seen this and does anyone know if there is a way to fix it?


    My OMV version is 6.0.25-1 (Shaitan).

    Please check /var/log/syslog for any error messages. If you do not find any, please run the following commands and then try to open the page in the UI again. Are there any errors shown in the CLI?


    Code
    # monit stop omv-engined
    # omv-engined -d -f


    Afterwards stop with CTRL-C and run monit start omv-engined.

  • Hmm alright. I will try again and post back here again.


    In the meantime, I do have these entries in  /var/log/nginx/openmediavault-webgui_error.log, but that doesn't really help much with solving the problem, I would think.

  • The time omv-sysinfo command has been running for about 10 minutes and it's not done yet. I will post an update when it's finished, but for now, OMV lists my CPU as Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz. The machine has 8GB of RAM.


    As for the plugins I use, here it the list of what I have installed:

    1. openmediavault-cputemp 6.1.1
    2. openmediavault-fail2ban 6.0.2
    3. openmediavault-flashmemory 6.1
    4. openmediavault-omvextrasorg 6.0.8
    5. openmediavault-remotemount 6.0
    6. openmediavault-sharerootfs 6.0-4
    7. openmediavault-symlinks 6.0.4
    8. openmediavault-wol 6.0.1


    I also use several Docker containers, but I would that that they would be irrelevant.

    fail2ban is working overtime blocking on the scans on your ssh port since it is exposed to the internet. And while it seems to be doing its job, I would highly recommend moving ssh off port 22. I don't know why that is slowing down omv-sysinfo other than the raw amount of entries.

  • votdev After clearing all of my fail2ban entries and trying again, the command runs instantly and the timeout no longer happens when using the web UI.


    ryecoaaron I can certainly move it, but I thought that the way those scanners typically worked meant that it would still get hammered. I would actually like to close it off, but unfortunately, I need SSH access to be open.

    Most of the scanners check regular ports for speed reasons. You could set it to 20123 and I doubt you would see any traffic. And I'm not suggesting closing the ssh port just changing it to a different port (I do).


    ssh hostname


    becomes


    ssh -p 20123 hostname


    And you wouldn't have to change the port on OMV just on your port forwarding 20123 (wan) -> 22 (lan)

  • FWIW - came here for this issue. I noticed when I went to reinstall Docker that it returned a "DNS Error". I'd been using Adguard Home with DNS-over-TLS. Reverting to default ISP's DNS on my router fixed this. It also resolved this 504 timeout issue. It ALSO resolved the "Please Wait, Configuration Changes..." taking FOREVER. Now back to normal.


    I suspect that all the various networks I have were all having to time out on similar DNS error, causing everything to take too long and for this 504 timeout to trigger.


    Hope this helps. I'm going to investigate more. I may revert resolv.conf to 8.8.8.8 and see if I can operate that way while maintaining my router's DNS settings to use AGH.
