I just installed Moodle 3.2 over LAMP -rhel 7.3,Apache 2.4, Mysql 5.7, PHP 5.6.25) and the site worked fine for several days.
Three days in, LTI no longer authenticates. I have back tracked and checked all that I know to do but cannot and correct the issue. ANy ideas would be helpful. thank you.
Instead of launching a lab automatically, the LTI authentication window opens requesting login credentials.
