My client gets a
sec_error_unknown_issuer error message when visiting https://mediant.ipmail.nl with Firefox.
I can't reproduce the error myself. I installed FF on a Vista and a XP machine and had no problems. FF on Ubuntu also works fine.
Does anyone get the same error and does anyone have some clues for me so I can tell my ISP to change some settings?
The certificate is a so called wild-card SSL certificate that works for all subdomains (*.ipmail.nl). Was I wrong to pick the cheapest one?
