Hi everyone,
Our college has a new Webwork server in development (version 2.18). We are currently using version 2.16.
We are trying to set up the LTI connection with Brightspace for this new server. This is not done at our College. It is done at Central University (our college is one of its 25 campuses).
When they try to set up our server in the University's Brighspace test environment, the following issue appears: Has anybody had a similar issue before, and how was it resolved?
** Here are the settings we share with Central IT:
Register as a standard tool
Domain: https://146.111.197.215/
Redirect URLs: https://146.111.197.215/webwork2/ltiadvantage/launch
OpenId Connect Login URL: https://146.111.197.215/webwork2/ltiadvantage/login
Target Link URI: https://146.111.197.215/webwork2
Keyset URL: https://146.111.197.215/webwork2/ltiadvantage/keys
Under Roles, select “Send Institution Role.”
** Here is what has been done so far:
1) Checked URL Accessibility:
The keyset URL seems to be working (https://146.111.197.215/webwork2/ltiadvantage/keys ). When I enter it in a browser, I see the JSON Webwork's cryptographic info stored (see below).
2) TLS Compatibility:
We checked our server, and it supports TLS 1.3.
We still need the SSL certificate matching the site's name of the site.
It will be temporary until we swap from the old server to the new one. Could that be the issue?
3) LTI Configuration:
We double-checked the LTI configuration settings in WeBWorK.
The authen_LTI.conf file is correctly set up for lTI 1.3, and all necessary variables are appropriately configured.
3) LTI Key:
We searched about it and found that one possible issue was that the LTI_KEY variable was changed at any point.
We looked into the database and found no such variable, so we are unsure if we should investigate further.
4) Network and Firewall Settings:
We ensured that there were no network or firewall restrictions.
Please help us in the right direction.
