Additional notes:

Have this issue as well. There doesn't seem to be a nginx conf file in /etc either.

Any chance you have a resolution. I am seeing the same thing. I exec into the container and I see the following when running curl against the root path:

$ curl -k https://localhost:443
{"status":"unauthenticated","errors":[{"message":"user authorization required"}]}

Note: I do get a page returned (at least with curl/not with browser or through proxy) with:

$ curl -k https://localhost:443/login/canvas

docker-compose up -d needs to be ran as root... so sudo docker-compose up -d does it.

Output should be as such:

~/canvas-lms$ sudo docker-compose up -d
canvas-lms_postgres_1 is up-to-date
canvas-lms_redis_1 is up-to-date
Creating canvas-lms_webpack_1           ... done
Creating canvas-lms_jobs_1              ... done
Creating canvas-lms_githook_installer_1 ... done
Creating canvas-lms_web_1               ... done

The above proposed solution did not work for me. Bumping this in case someone found a solution

@ma-anwar would you be able to paste the issue you're having? I'll try to find some resources to help resolve it or get a fix going if one is needed.

Hi thanks for the quick response. I get the exact same error message and am able to reproduce using the exact same steps as the OP.

I suspect it may have something to do with Dory but am not sure how to proceed. Am trying to set up canvas LMS for lti development.
