nginx errors + where to start

Post by pattonb »

I have been updating a 8.7.6 zcs , I have it to 8.8.12, and suddenly, email clients can't send
or receive, the webmail works fine. I see the following the /opt/zimbra/log/nginx.log's

Code: Select all

zm lookup: all lookup handlers exhausted while SSL handshaking to lookup handler

zm lookup: ngx_zm_lookup_connect connect lookup handle error for host:x.x.x.x:7072
An error occurred in mail zmauth: no valid lookup handlers while SSL handshaking to lookup handler, client
all 3 errors are repeated over and over.
Not sure where to start, also cbpolicyd is not worjing, and from the logs,
ERROR: 2022/01/19-09:00:33 Can't connect to TCP port 10031 on ::1 [Cannot assign requested address]
at line 68 in file /opt/zimbra/common/lib/perl5/Net/Server/Proto/TCP.pm
is it possibly self signed certs causing the issue(s) ?

any suggestions ?

thank you

I think I found the root of the problem in looking at the installed/deployed crts I see.

Code: Select all

opt/zimbra/bin/zmcertmgr viewdeployedcrt
NOTE: imapd: file '/opt/zimbra/conf/imapd.crt' does not exist.
- ldap: /opt/zimbra/conf/slapd.crt
notBefore=Jan 16 10:31:39 2022 GMT
notAfter=Apr 16 10:31:38 2022 GMT
subject= /CN=blah.blah.com
issuer= /C=US/O=Let's Encrypt/CN=R3
so how does one generate a new imapd.crt ?

thank you

the imapd.key has been resolved, however the nginx errors still remain a mystery to me.

Code: Select all

1023 An error occurred in mail zmauth: no valid lookup handlers while SSL handshaking to lookup handler,]
and

Code: Select all

1023 no memcache server available, cannot post request while in mail zmauth state
are 2 of a few errors, I see over and over. does anybody have any idea ?

thank you
