Firefox will report sec_error_revoked_certificate with OCSP enabled, on both 39 and 40.
IE 11 on Win 8.1 also reports certificate revoked.

I've checked with the following combinations, and all of them work:
Safari on OSX
Chrome on OSX
Gnome-web on Linux
Chrome on Linux

By the way I also checked OCSP itself with gnutls, no problem there.
Please tell others you know about this if they have problems getting into yande.re.

UPDATE:
After checking gnutls's output once more I noticed the certificate has been revoked in OCSP responses.
Probably a new certificate is required.

Same here for Firefox latest beta (41b7) on Win7.

Not happened on chrome latest beta (46.X beta-m) though (not sure if i've disabled something previously).

But from revocationcheck, it said cert is revoked.

Hence the error "sec_error_revoked_certificate" as mentioned in the OP.

But this can be bypassed by disabling a certain setting (also mentioned in the OP), unlike the expired cert error.

yeah, i got the same problem..in firefox,opera, chrome, ie...but in firefox can be solved bu uncheck OCSP, in ie..can be solved by uncheck this

hope someone can give explaination...

I am as clueless as you are, I'm waiting for the upstream provider for an explanation. The fact that it is labour long weekend made it twice the shit.

I've rang all the bells I can and I'm just waiting.

お疲れ様でした!

Apparently it's fixed now. Thank you!

Same here. Thanks a lot!

Yeah, seem already fixed, thanks :3
