Site Operators Tutor Help

I am trying to access my Open edX instance sign-in or Register at:
:link: https://apps.www.lms.xxxxx.com/authn/register?next=%2Fcourses

However, I keep getting the following error in my browser:

“This site can’t be reached. Check if there is a typo in apps.www.lms.xxxx.com. DNS_PROBE_FINISHED_NXDOMAIN”

Please let me know how to fix this issue.

I don’t know if I could help you but could you edit your post with more information?

  • What version of Tutor are you running?
  • Is this a new installation?
  • What have you done to debug?

I think that on Sumac login should be directing you to a differently named page but it will be hard to help you debug without more information.

This indicates that you have not configured your DNS correctly so that it can resolve your domain name into an IP address.

Typically you might create your records like this:
base server address - this will be an A record in your DNS
lms.domain.com
sub addresses - these will be CNAME records pointing back to your A record above
apps.lms.domain.com - required for MFE
studio.lms.domain.com - required for the Studio/CMS
meilisearch.lms.domain.com - required for the indexing service

you can use the nslookup tool to test if your DNS is resolving correctly, eg:
nslookup apps.lms.domain.com 1.1.1.1 (perform lookup, choose domain to lookup, use cloudflare to lookup - the last IP is optional, otherwise it’ll use your primary DNS server on your network)
example of output:

nslookup google.com 1.1.1.1
Server: one.one.one.one
Address: 1.1.1.1
