Hi Pascal,
this is either a bug report or a feature request, depending on how HTProtect is supposed to behave.
On my website, I use a different method to secure backend access than the additional password protection from HTProtect. That’s why I haven’t enabled HTProtect’s Backend Access protection.
This not only causes the System & Self Test to show "3 of 4 passed" (Backend reachable (401 = password protection active) shows "Check"), but (probably) also causes automatic extension updates to roll back repeatedly, forcing me to update manually.
If this is intended behavior for HTProtect, it would be great to have a toggle to deliberately disable Backend Access protection, and for the related System & Self Test to be removed or ignored so that automatic extension updates can work without Backend Access protection enabled.
Cheers
Tom
