With some Uploads in Moodle (3.9) Uploads are not successful, mainly pdf.
The message that comes up is: "An error occured whilst communicating with the server".
not successful requests show
POST /course/dndupload.php undefined
successful requests show
POST /course/dndupload.php HTTP/1.1
When a pdf is reexported with libre office for example the same pdf can be uploaded without problems.
any ideas?
Is the LibreOffice pdf smaller? It could be PHP timing out.

What is the value for max_execution_time ? You can check the PHP values here -
Site administration > Server > PHP info
Also, try switching debug to developer level and see what the error message is.
Site administration > Development > Debugging
Debug messages = Developer
Display debug messages = checked
Although be cautious changing the debug level if its a production site. If you have access to the config.php file then you can specify a user.
// You can specify a comma separated list of user ids that that always see
// debug messages, this overrides the debug flag in $CFG->debug and $CFG->debugdisplay
// for these users only.
// $CFG->debugusers = '2';
Thanks for the response, in the meantime a solution to the problem was found. On the server a measurement against log4j2-vulnerability has been implemented: https://support.f5.com/csp/article/K59329043#proc2. This caused the misbehaviour, the iRule has been removed, now it works again.

All of a sudden we are seeing this random error / exception in our web application.
Failed to load resource: the server responded with a status of 502 (Bad Gateway).
In the Log Stream, we are seeing the following details, with specific error code as 502.3 - Bad Gateway: Forwarder Connection Error (ARR).
Also, sometimes in the browser itself we see "The CGI application did not return a valid set of HTTP errors." getting displayed.
Most of the searches for these error codes refer to "IIS / Proxy Server" configuration. But, we haven't changed any such settings.
The error happens very randomly and not specific to any user action/function. Same functionality works first and on second execution immediately after first one throws this error.
How to figure out what is causing this and how to fix?
I google this question, because the program was normal at the beginning, and the subsequent 502.3 error. After I checked the information on the Internet, I feel that it can only give us an inspiration, and it cannot solve your problem immediately.
So my suggestion is that first you browse post1 and post2 I provided.
Next, proceed to Troubleshoot according to the steps of the official documentation. Specific errors require specific analysis.
The website URL works fine. The link from google maps on the phone works fine. For some reason when you google it in the browser (mobile browser or desktop) you get an Internal Service Error. Google said it was nothing on their end to be done.
Has anyone encountered this or have an idea of what's causing it? The error received is below.
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator and inform them of the time the error occurred, and the actions you performed just before this error.
More information about this error may be available in the server error log.
Apache Server at www.thetechbuyer.com Port 80
As the error suggests, an Internal Server Error is internal to your webapp or web service on your host. It usually means that your program, whatever it is doing, has crashed. This could be because of misconfiguration, or a bug in your code, or something else - without knowing more (possibly a lot more) about your server environment, it is impossible to know what.
Check your server logs - they should have more information.
(It also isn't clear what this has to do with Google+.)
I have a file on AWS S3 that is public:
https://s3-eu-west-1.amazonaws.com/voxist-greetings/33631222504/33651291239_95113eed-386b-4264-a4cf-46182faae125COUCOU1.wav
Now when RVD try to play it I get:
INFO [org.mobicents.servlet.restcomm.interpreter.VoiceInterpreter] (RestComm-akka.actor.default-dispatcher-8586) MediaGroupResponse, succeeded: false jain.protocol.ip.mgcp.JainIPMgcpException: The IVR request failed with the following error code 312
I don't know why... The same file used to work with another name.
Thanks for any hint on how to debug this.
The problem seems to happen on Media Server side. More specifically, it seems the file cannot be opened for some reason.
Relevant code line can be found here.
Can you please take a tcpdump and share it, so we can see the MGCP Play request?
Hope this helps.
UPDATE:
Here is an example:
The 200 OK simply indicates that the MGCP transaction completed successfully. Now we need to dissect the notification (NTFY) sent from Media Server to RestComm, mainly the ObservedEvents parameter.
If you look at the picture, you will see the event triggered is an OperationFailed (of) with ReturnCode (rc) equal to 312, which is an error.
Relevant link to specs can be found here.
To summarise, Media Server receives the request to play the file (in this case a cached version of it) but if fails to open the URL for some reason.
Is the URL reachable from Media Server side?
i have the following simple script to list the ftp accounts
but i am unable to get it to work as i have the following error as soon as it tries to call the constructor
include '/usr/local/cpanel/php/cpanel.php';
$cpanel = new CPANEL(); // Connect to cPanel - only do this once.
// List FTP account information.
$list_ftp_accts = $cpanel->uapi('Ftp', 'list_ftp');
echo "<pre>";
print_r($list_ftp_accts);

According to a post on the cPanel forums, you can only use LiveAPI from within cPanel's document root, meaning your code would need to be in either /usr/local/cpanel/base/frontend/ or /usr/local/cpanel/base/3rdparty/. I ran into this while trying to use it in a WHM plugin (which would reside in /usr/local/cpanel/whostmgr/docroot/), and apparently that causes the same problem. If you're trying to run this from within cPanel or WHM, this page has some debugging steps you can try walking through.
If you're trying to run this code on a different server or from within a normal website's hosting account, you'll definitely need to use a different interface, such as the XML or JSON API. These are unfortunately somewhat confusingly documented, but the Guide to WHM API 1 page should get you started.
Me too got the same error.
Try changing your file extension to your_file.live.php, instead of your_file.php. It solved the issue for me.
Referred the documentation here.
In case of compilation error Resin shows a simple page with the only message:
Server Error
The server is temporarily unavailable due to an internal error. Please
notify the system administrator of this problem.
And all significant information I should seek in the log file.
Is it possible to redirect somehow all error diagnostics to the browser window?
Try setting <development-mode-error-page/> tag to true. In later versions of Resin the value is externalized into resin.properties:dev_mode
