I've been logging into Stack Overflow with my Openid.org account for a long time, but it doesn't work anymore.

I tried to verify my account by logging into Openid.org just now. I was successful, and it seems my account is fine.

I tried the following URLs on Stack Overflow:


I always get the error messages below:

Unable to log in with your OpenID provider:

No OpenID endpoint found

I do received the recovery email in my email box including openid.org/nanohe. But followed the same openid URL link, I still can't log into Stack Overflow.

Can anybody help me? I appreciate your help.

  • @Marc Gravell. How to recover it? Or can I transfer my stack Overflow openid.org account data to my another new open ID bind with google.com? – Nano HE Nov 22 '10 at 10:05

    That https isn't going to work with a borked certificate. – Marc Gravell Nov 22 '10 at 10:13

I don't know if it is the root cause, but their SSL certificate has expired (18/09/2010) - #fail:1. This does not bode well..

Registering to test it; they sent me back my password in the confirmation e-mail - #fail:2

IMO, that openid provider is borked - most likely the SSL certificate is blocking everything else. Your meta account is enough to demonstrate ownership of your SO account, so my suggestion would be to add a second openid to replace this one. For example, myopenid or gmail. Gmail is slightly problematic, since it varies per-site (meaning: I can't simply clone the data between SO and meta.SO), but if you create a new SO account against a gmail I can merge the two.

Either way, yes we can recover your account.

  • Yes, I would like to generate another account bind with myopenid.com. <br> Attached the information below <br> stackoverflow.com/users/483960/nano-he <br> nanohe.myopenid.com <br> Could you please merge to the new one. Thanks a lot. – Nano HE Nov 22 '10 at 10:17
  • @NanoHE - try now – Marc Gravell Nov 22 '10 at 10:22
  • It works quite well now. Thank you very much. – Nano HE Nov 22 '10 at 10:29
