Hi, I have TAO and devkit on the same server. In TAO, I changed the configuration in the file usr/local/libexec/tao-ce/setup/apps/construct.libsonnet (screenshot). In devkit, I’m trying to open a test request on:  
[https://ims.dev.domain/backoffice/ltiDeliveryProvider/DeliveryTool/launch1p3?delivery=https%3A%2F%2Fcommunityedition.tao%2Fontologies%2Ftao.rdf%23i69899853154dc20260209081827790c8a7c](https://ims.dev.domain/backoffice/ltiDeliveryProvider/DeliveryTool/launch1p3?delivery=https%3A%2F%2Fcommunityedition.tao%2Fontologies%2Ftao.rdf%23i69899853154dc20260209081827790c8a7c),

but I get the error “No matching registration found tool side”. The public and private keys are the same in TAO and devkit. Maybe I didn’t register the devkit correctly in TAO, in previous versions it was done through the admin interface, but in the new version it’s not available, can you please tell me what I might have missed? Maybe there is a connection instruction for the new version somewhere?

Dear Rusian,

Thank you very much for your message, I will have to follow up internally as this is obviously a more advanced technical question.

Best Regards,

Patrick

Dear Rusian, I have received this early feedback,

“\*The given error comes from his LTI platform, defined at LOGIN\_INITIALIZATION\_URL

Probably it cannot match registration with `client_id` and `secret`  
Again, probably he need defined somehow like here  
[https://github.com/tao-ce/tao-ce/blob/develop/libexec/setup/apps/files/environments.libsonnet#L350-L351](https://github.com/tao-ce/tao-ce/blob/develop/libexec/setup/apps/files/environments.libsonnet#L350-L351)

Or make it like that one  
[https://github.com/tao-ce/tao-ce/blob/develop/libexec/setup/apps/files/environments.libsonnet#L14-L17](https://github.com/tao-ce/tao-ce/blob/develop/libexec/setup/apps/files/environments.libsonnet#L14-L17)

But for now, there is not enough information to get it for sure, better to see networking to understand exactly where it stops\*“

I hope it does help at this stage or at least allow us to capture more data from networking to identify this issue.

Regards,

Patrick

Dear Patrick, thank you for your feedback. Unfortunately, it didn’t help me, or I’m doing something wrong. The fact is that in the previous version of TAO, there was a tab in the admin panel for LTI connection settings, which is not present in this version, why was it removed? The instructions for TAO say that the connection configuration is configured by the TAO administrator, but in the new version, the administrator does not have this functionality. Editing files inside a docker container is very difficult and it is not clear what parameters to enter and where to get them from. I would be very grateful if you would give detailed instructions on how to connect TAO via LTI 1.3.
