Changing hostname from fog broken

@dejv said in Changing hostname from fog broken:
The remote server returned an error: (502) Bad Gateway.
Looks like the fog-client can’t get a proper response from the FOG server. Please check the Apache and PHP-FPM log (see my signature).

Below please find the logs.

@dejv The Apache log seems to be very recent (“May 24”). Depending on log rotation the errors might be in an older log file. See what you have in /var/log/apache/… Or make sure the fog-client is still trying to access the server. In that case we should still see more recent errors in the logs.
The PHP-FPM log looks very old on the other hand. No idea why the log ends in October 2020?!

@sebastian-roth If I redownload Fog and reinstall it will it fix the issue? (hopefully it will keep all settings)

Well, without further information we don’t know what is causing the problem. Therefore I can’t tell you if re-installing will help either.

Tried redownloading and installing fog as its pretty easy and straightforward however still same issue.

That might be a first hint on what might be causing the problem. But on the other hand I am wondering why it’s calling register.php. Is this client registered in FOG already or not?
-
yes client was registered already
-
@dejv Found some time to look into this and I think I was on the wrong track. I looked through the code and I don’t think that part can be triggered by a registered client. It does not match what we see in the fog-client log file. As well the logs posted last (that include the register.php call) are from May 20. But the fog-client log posted earlier is from May 21. Just doesn’t match.
So let’s try to tackle this from a different angle. What happens if you open the URL http://fog/fog/service/getversion.php?clientver&newService&json in your browser on a normal work PC?
I ask because in the fog-client log we see that URL request triggered a HTTP 502 Bad Gateway error and I am wondering if you see that when opening the URL manually as well.

Thanks
I am getting the below number when accessesing the following link: http://192.168.0.58/fog/service/getversion.php?clientver&newService&json
0.12.0

0.12.0While this sounds like it does work as it should the version number is different to what we saw in the fog-client log. When you re-installed the FOG server did you use the latest dev-branch version?
Possibly you are hitting a different error now. Please post the latest fog-client fog.log here so we see if it’s still the same problem or a different one.
Are your FOG server and the client machine in the same subnet? No router, gateway or maybe proxy server in between? I ask because we had someone with very strange fog-client issues that were caused by a proxy server. The fog-client seems to be using the global Windows proxy settings.
-
I downloaded from : https://github.com/FOGProject/fogproject.
Fog server and clients are on different subnets however have been like this for around 2years, I have a sophos utm router, without proxy

@dejv In the fog.log we see the hostname
fogin the URL - http://fog/fog/management/… Does this hostname resolve to the IP 192.168.0.58?Do you have just one FOG server (master node) or other FOG storage nodes as well?
Please run
ls -al /var/www/{,html}as terminal command on your FOG server and post the full output here. -

@dejv Can you please run:
sudo -i mv /var/www/fog{,_back} ln -s /var/www/html/fog /var/www/fogThis should help fix the fact that your environment sees 2 separate fog instances (one in /var/www/fog and one in /var/www/html/fog with the one in /var/www/html being the newest version.)
The commands I give will move the /var/www/fog to /var/www/fog_back (you can simply delete this if you feel comfortable to do so.)
Thank you,

@tom-elliott I tested on another computer and its working.
on this particular pc its not working. I will try and uninstall fog client from the pc and reinstall it again and will see if it works.
IF it still doesnt work will try to remove from fog server and re add
