Initial symptoms...
Diagnosed and solved:
This is just... strange. On many clients, I have no issues logging in to ProxMox.
On a few, suddenly I can't. Used to work but not anymore.
The symptom: clicking on the login button does nothing at all. ALWAYS. No errors. It just does nothing.
I have no blockers in place.
On more detailed examination:
- The language entry, which says "English" is red-bounded as if in error. The (i) error says "value 'English' not allowed."
- If I attempt to select "Default - English" I get the same.
- If I select another language, the dialog box does change to that language, but the entry shown remains "English" and has the same error.
Diagnosed and solved:
- My password/form helper remembered an earlier version of the login form
- It used to use "English" but now uses "Default (English)"
- By forcing "English" into the form field, it silently made it impossible to login
