I am still pre-0.30 and to verify some gitlab pages I need a new TXT record. However, it’s not working and I have done this before - namely as a challenge to obtain a certification via letsencrypt. However, I have this:
I just did a dig for the TXT record from your MiaB and it did not come back. Please check in the admin area System>Custom DNS that the entry is present. I suspect that it is not. You can add it from that page.
This might be a bug in the API you used (specifically for TXT records?) so a report on github as @alento recommended would probably benefit the developer too. In this case, I redact my previous statement.
And to add to this question, WHY haven’t you updated to post-0.30? I see no standing benefits to this unless you have made some modifications to your MIAB installation and cannot update to Ubuntu 18.04?
Functionally, v0.30 and v0.41 are identical however the developers are not supporting the older version anymore, so it would be a requirement to upgrade first as their response will be to upgrade. Would you be willing to PM me a copy of your /home/user-data/dns/custom.yaml file?
