FWIW, 7:29 PM shall be understood as 17:29h GMT (5:29 PM GMT) because I am in GMT+2 right now.

Checking a former post by myself about CCC Archive:

Re: CCC archive no longer working?

I looked in the first and second SSL web checkers:

• sslchecker.com says 'No certificates were found' when I checked the default port 443 suggested by the SSL web checker.

• sslshopper.com says '[IMAGE OF A TICK] forum.computerschach.de resolves to 85.214.74.225 ; [IMAGE OF A WARNING SIGN] No SSL certificates were found on forum.computerschach.de. Make sure that the name resolves to the correct server and that the SSL port (default is 443) is open on your server's firewall'.

It's not the first time, that SSL certificate was forgotten to get renewed at CSS- site, regards

Same here. But it doesn't really bother me. After all, the forum often doesn't focus on chess anymore. Unfortunately, other topics like math and puzzles have taken over.

Can you tell us more about that?
