On windows i did a IIS restart and now my problems are solved. But what do I do with the old and now expired certificate. Can I delete it safely ?
I would let things be for a while.
"If it ain't broke, don't fix it."
I can't understand one thing .. does this problem fix itself? or you need to make some changes .. I'm not so practical .. can you explain me better?
Many old windows users have problems with https
Have you changed or performed something? Or simply restarted IIS?
Thanks you saved my day! Missing mails on postfix
SSL_accept error from xxx.xxx.xxx: -1

I also did a update of Certify the Web. Then checked ssl labs, and everything was ok. Funny enough, one issue was a certificate that I have to manually update. I,m using a temporary website only to get the certificate and then use the certificate for my mail server. All the other websites do auto renews and worked perfect,.
I am using certificate in shadowsocks app on android 7, everything worked until yesterday. Now the certificate only works with Windows 10 and Android 10 in the shadowsocks app. Please tell me how to make the certificate read on android 7 without errors.
I created the certificate this way
acme.sh --issue -d domain.name --dns dns_cf --server letsencrypt
In some cases... maybe.
In most cases, yes.
They may need to update their root stores.
You probably need to update the chain used.
Which chain does it serve now?
Which cert files did you use?
I am using two files
As of today Chrome on my Windows 7 stopped pulling up all sites encrypted with letsencrypt. Very peculiar as Chrome on my phone and laptop (Win 10) work just fine. Even more peculiar is that when I try to pull up a site (e.g. https://colossus.media), Chrome will sometimes simply say ERR_TIMED_OUT, but sometimes will complain about NET::ERR_CERT_DATE_INV
Drives me crazy. Spent all day troubleshooting this. Nobody else I know is having this issue. I would assume it's my PC, but the fact that it happened on the 30th.... Hmm, strange.
Firefox works great.
You can remove DST Root X3 from the ca certificates.
I described how it works on an old Debian wheezy with OpenSSL 1.0.1:
Does that solve the problem? I have IIS running
Can't make it work on some devices (Windows 7 included).
What I have tried so far:
- deleted all X3 and R3 expired certificates
- use PSExec to see certificates and delete it (suggested in another thread)
- generate new certificates
- restarted IIS
- restarted server
- restarted client
- changed the Preferred Issuer to "ISRG Root X1"
Any different suggestion? Thanks.
Does what solve the problem?
OK, I would try:
remove the last (bottom) certificate
[there should be three certs in there]
Did you open the Certificate control panel with local computer ? Is you open it as a user and make modifications it won`t work. ( silly answer, but hey, some are using cert manager as a user for computer based certs.)
I suppose Chrome is using it's own certificate store.
And you would need to get in there and add/remove the expired cert.
Yes, Actually I tried in all of them. User, Local and Service.
