Hello, please help solve the problem:

I try to integrate Moodle 3.5 and Mahara (19.04 git install - github.com/MaharaProject/mahara/commits/19.04_STABLE  7okt commit b09a9fa133a781f00b3c22db89786f8bca95bda6).
In Mahara:

enable Network + add moodle host to Institutions with its public key

In moode:

enable Mnet
add mahara site  with its public key
select mnet subscription/publication
add right in Authenticated user role
add block with link to mnet site (with link to mahara host)

But when click on the link from moodle - mahara site opens with error:

mahara.arcticsu.ru: Site unavailable

A nonrecoverable error occurred. This probably means you have encountered a bug in the system

... URL in browser address bar likes as follow:
mahara.arcticsu.ru/auth/xmlrpc/land.php?token=127746d0e1e03a9d7b296a89e3363b3752ee1e6c&idp=https:||moodle.nnn.ru&wantsurl=

In Apache log of mahara host the following error:

Hi Pavel,

Did you follow the setup instructions document found on the wiki? It displays an old version of Moodle, but the steps are basically still the same.

Did you make sure to select "Mahara" in Moodle as application and not "Moodle" by accident?

Does your URL contain any special characters? That seems to be the recurring message in your error log (see line 1)

I haven't come across this error yet and thus don't have a ready answer.

Cheers

Hi, Kristina.

> Did you follow the  setup instructions document found on the wiki? It displays an old version of Moodle, but the steps are basically still the same.

Yes

> Did you make sure to select "Mahara" in Moodle as application and not "Moodle" by accident?

If you mean Application type on  Add a new host screen - I think yes ... but I can't find where I can check this.

> Does your URL contain any special characters? That seems to be the recurring message in your error log (see line 1

I been forced to change URL  because this mahara site didn't allow to post URL links in messages

Can this problem be related to fact that I use GIT version from 19.04_STABLE branch, which STABLE but is under development? From you sight - is it make sense to downgrade or try version which is published on mahara official site?

Hi Pavel,

Using Git is fine. The latest code on the 19.04_STABLE branch will be the next minor point release. If you want to use what is being released, look for a release tag and choose that version then rather than everything that is on the stable branch.

I think you may need to check in the Moodle database table to see if the application type is set correctly.

Cheers

.. in addition.
Can problem be related with bad redirection URL?:

https:||mahara.arcticsu.ru/auth/xmlrpc/land.php?token=a0179187d0907902e1b465f054016ab5a02db694&idp=https:||moodle.arcticsu.ru&wantsurl=

... in the end - variable wantsurl= is empty

... on both sites - there is apache-host redirection from http-host to https-host/

Hi Pavel,

I'm not sure if you've sorted out your problems or not but the 'wantsurl' is set if you try to access a page in Mahara that you need to be logged into but are not yet logged in, eg if you go directly to eg, 'view/view.php?id=5  it will send that path along to the external login so that when you are verified you will return to that place rather than the index page.

If it is empty it just means you will end up on Mahara index.php page in successful login.

So I don't think it's the cause of your login problems.

Cheers

Robert

Hi there,

I am facing the exact same problem as you. User authentication through moodle used to work just fine, but after some time I am getting these errors. I also use moodle 3.5 and mahara 19.04.

Did you manage to fix this?
