Hi, Since the firefox and chrome latest releases, we are facing a lot of issues with our etherpad in Moodle, "No access to pad"...
We use etherpad for our moodle + redmine, both are running with the same server, with reverse-proxy,
The only differences are regarding access configuration
+ slightly version difference : moodle instance : 1.5.7 sur redmine instance : 1.6.0
I wonder if others are facing the same issues ??
Thanks
Emilie

Hi Emilie, even if we have also heared of such things, we have not been able to reproduce them in our environment by now and to debug them. Hopefully we will find the time to release an up to date version which comes without such issues.

Hello, I just updated my server from Windows 2012r to Windows 2016. I start getting the following error when I try to open old course's EtherPadLite or create a new one: "Exception - Empty or No Response from the server" on Moodle 3.1. It worked fine on Windows 2012r. Also, when I run EtherPadLite directly, without Moodle, it works fine. Any ideas? Thanks, Eugene
PS I also had problems with accessing Question bank on Moodle after Windows update, but I solve it by lowering the version of PHP from 7.0.9 to 5.6.30 (64-bit). This did not help with EtherPadLite....

Update on the "Exception - Empty or No Response from the server" error. With the help of our IT colleagues, I found problems with my DNS settings on my network adapter card. Also, IPv6 causes problems as well and has to be disabled on my network adapter. Etherpad works. The problem is solved.

Hello Eugene, we're glad to hear that the problem wasn't a persistent and generic ep problem and at least is solved

Hello dear community,

We upgraded our Moodle to 3.5 and hoped that Etherpad 2.7 would still work. But we get the following error when creating an activity:
Empty or no response from the server

The apache log:

Database transaction aborted automatically in /srv/www/htdocs/moodle/course/modedit.php, referer: ...

Default exception handler: Error: Empty or No Response from the server Debug: \ nError code: generalexceptionmessage \ n * line 107 of /mod/etherpadlite/etherpad-lite-client.php: UnexpectedValueException thrown \ n * line 60 of / mod / etherpadlite / etherpad-lite-client.php: call to EtherpadLiteClient-> call () \ n * line 148 of /mod/etherpadlite/etherpad-lite-client.php: call to EtherpadLiteClient-> post () \ n * line 62 of /mod/etherpadlite/lib.php: call to EtherpadLiteClient-> createGroup () \ n * line 124 of /course/modlib.php: call to etherpadlite_add_instance () \ n * line 154 of /course/modedit.php: call to add_moduleinfo () \ n, referer: ...

If we call Etherpad directly and not via the Moodle plug-in, it works. Our assumption that Etherpad-lite 2.7 for 3.5 is not compatible seems to be confirmed.

Did anyone get Etherpad Lite running at 3.5?
Are there plans to further develop Etherpad Lite for Moodle 3.5?

Excuse me if my english is bad. The Google translator helped.

Best regards,

Egor

Hi David,
Thanks for the question. But could you please use the right place for your questions?
If you have questions like this you can post them in the general plugins forum (https://moodle.org/mod/forum/view.php?id=44).

My students and I started getting errors on EtherPad after I updated to Moodle 3.8.3+ (Build: 20200527), the Etherpad plugin for Moodle version 2019013100, and Etherpad Lite server to 1.8.5. We cannot open an etherpad. The problem is unpredictable but it appears when 20-30 users access an etherpad embedded in Moodle at the same time. Here is a typical error message:

ErrorId: 4wNmhAZ2hYo9zBrq1xHb
URL: https://myaddress:9001/p/g.NfRQhXclxTNNzHYW$DiaMoodle
UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:80.0) Gecko/20100101 Firefox/80.0
TypeError: $sidedivinner is undefined in https://myaddress:9001/static/js/require-kernel.js?v=c4855223 line 1 > Function at line 5

We do not have a problem when we use Etherpad directly without Moodle.

I never had this problem before with previous versions of Moodle, plugin, or Etherpad Lite Server. Any ideas what cases it and how I can resolve it, please?

PS I set minify to false and AgeMax to 0 in settings.json of Etherpad Lite Server. It seems to help a bit but not completely...

Hi Eugene, please use the forum (https://moodle.org/mod/forum/view.php?id=44) for this sort of question. This area is for comments only.
Thank you!

I love Etherpad. How do I get the API key or host?

Untill Version 2021073000 the Etherpad Plugin worked for us. In newer Versions we got the Error: Could not get api version
Now I debugged a little bit and found out, that in the file
etherpadlite\classes\client.php in the function get_version() the
$url = $this->baseurl;
ends with
/api
and not with
/api/
what leads to an Etherpad instead of the JSON. After adding the missing slash with the following code it works for us:

if(!(substr_compare($url, "/", -1) === 0)){
$url.="/";
}

I was able to get rid of the error message "Could not get api version". so now I can create a pad in Moodle, however I cannot access it within Moodle.

The error message I get is "pad.igmetall-moodle.de has refused the connection."

Best regards
Guido

Thank you for your understanding!

If you want to use apikeys with Etherpad-lite Version 2.. then this must in the settings.json
/*
The authentication method used by the server.
The default value is sso
If you want to use the old authentication system, change this to apikey
*/
"authenticationMethod": "${AUTHENTICATION_METHOD:apikey}",
