Glad to hear problem identified!!

Would you like to share how validate the certs in PASE for Zend Server ?

Cheers

Well thanks to Larry B we have identified the problem.

The main cert was valid but due to an error by Comodo one of the other
certs in the chain expired on the 30th of May and not in 2021 the same as
all the other certs. Sigh.

Interestingly this only causes an issue when the server restarts. We had
to Re-IPL and restart the servers after the PTF install - hence the
apparent connection between the two events. Quite why an expired cert
continues to work as long as Apache is not restarted I will leave to
better brains than mine to explain!

Hopefully we'll have new certs issued tomorrow and all will be well in our
little world.

Thanks to everyone for the suggestions. I can at least now validate and
view all my certs - both the DCM managed ones and the PASE ones for Zend
Server.

In that case it's most likely ciphers were disabled with the PTFs on

side. I've had a quite few customers have this issue with PTFs in the

last

month or two.

And it's not always just that simple. One for example had a cipher list

their server with some obsolete ciphers that were not in my customer's

list

(my client was making requests to their server). But, at least 8 others
matched. It still errored out until I added that one obsolete cipher

back

into my list, which I didn't want to do because I didn't want to

override

the system settings for SSL. Why? If I forget I'll have the opposite
problem with new ciphers that are added.

SSL on the IBM i has always irked me for reasons like that, and for

expired

CAs that cause all SSL to fail whether related to the communications or

not.

Yup - did that Brad. they all appear OK.

This started happening after we applied a couple of group PTFs so i'm
wondering if that is part of the problem.

Well, if it is anything like DCM, even an expired CA that has nothing

with your communications can sometimes cause problems. You may want

Thanks - that has saved me a lot of trouble as it showed that the

Time to involve someone who knows what the heck they are doing!

Thanks again.

Can you share the config details for the application link to use the

main cert - I could not find how to configure that.

have

an application defined, and in the apache setup we use the SSLAppName
directive to point to the certificate. If it's a connection

elsewhere,

use

openssl to look at the cert. Something like this:

openssl s_client -connect ibmsystemsmag.com:443
