failed to validate LTI request message

Canvas uploading assignments and course content from onedrive does not work, instead came back with an error message [Failed to validate LTI request message]

@losa Whenever I get a message like this, it is temporary and resolves within a couple of hours.

Thanks for your feedback. Its our second day with this issue, still exploring and reaching out to Microsoft for support.

Hi @losa ,

We are currently experiencing this issue as well. It began around 11:00pm AEST on the 25th Feb.

I am unable to access the OneDrive LTI admin/registration page (https://onedrivelti.microsoft.com) - it just turns up a blank screen.

I'm currently communicating with a support agent at Microsoft to determine where the issue lies.

Hi @PeterSercombe, it will be great to find out the underlying issue, it's our second day without accessing OnedriveLTI.

Our Organization is also having this issue. Getting error "Failed to validate LTI request message"

We've logged support cases with both Instructure and Microsoft.

From the Microsoft Premier Support case we logged, we havn't heard anything back yet. We provided in the Microsoft ticket the Instructure ticket# so they can liaise through their Partnership Program and hopefully resolve this as quickly as possible.

We're in the same boat.. Just finished logging tickets wtih MS and Canvas to invistigate..
Not a good time for this to fall over 😕 Week 1 of first semester!

This was resolved by Microsoft yesterday. 

This was the note they provided for me outlining what they suspected to be the cause. 

We will consider the case as resolved after the fix for the issue "SharePoint - site members encounter Access denied issue" or if it is identified to be caused by a third-party, out of support or is proven by design.

What was the solution? I do not see it here?

We are now seeing this issue with our students trying to use Collaborations within their Canvas courses - did anyone ever hear back on the cause or have a suggestion for troubleshooting this issue?

[B-Hazelwood]

This issue was fixed for us my Microsoft back Feburary. the cause was a MS issue they knew about, lasted about 4 days.

After your msg I just checked ours again and it failed lol. Bad local cache was the problem this time - it has been a few months since I've been in our collaboration space on a course.  @amyslack have you tried an incogneto browser?
