Same question but a few months later. Had to re-install DO from 12.2 installer. I can see there is an update to 12.33 when I go to "check now" but the download never starts.
When I try to follow the link provided above I get "This site can't be reached" DNS_PROBE_FINISHED_NXDOMAIN
I have also tried Download Opus - Directory Opus Self-Service Support from the "Download older versions" link on https://www.gpsoft.com.au/, but same result.
How to I update to 12.33?
Thanks for thte "Tor tip"!
Just had the same problem (also from Spain) Had to re-install W11 and it gave me the same error.
Thankfully Tot worked!
Cheers!
