Forum LAMS for Tech-Heads - General Forum: Re: Re: Re: Re: Re: Re: Re: LAMS MOODLE 3.0x Integration not working

Actually lesson creation is still broken or it broke by itself (can't remember if it actually did work). Since last week we only had to grade finalized sequences I forgot to test. But now students ran into this in another class:

When clicking on "Update this LAMS session", one has to wait a few minutes then get:

Call to LAMS failed: received no response or connection was refused. Please check that you have the correct LAMS server URL and that it is online.

error/lamslesson/restcallfail

Any ideas why this happens ?

In the apache log I can see the following:

Using:
LAMS 2.4
Ubuntu 14LTS

I also noticed that Moodle detects a huge lag which is strange since both Moodle and LAMS sit on the same machine and host.

LAMS time: 01-01-1970 01:00:00.000000
Moodle time:06-02-2016 15:47:29.000000
Offset: -24414587.48515 minutes
