ZCS 8.8 upgrade Proxy port problem

[MisterM75]

Hello
Since the update I no longer know how to access the webmail.

Via port 8443 no worries, via port 443, here is the error message:

ERR_EMPTY_RESPONSE

For the message below we forget, it is functional:

warning: /opt/zimbra/common/conf/main.cf, line 819: overriding earlier entry: smtpd_milters=inet:localhost:11332

Thank you for your help

If your question does not relate to Rspamd you should start a new thread, I've moved this post to a new thread. Don't forget to search the forums & wiki before you pots, most questions have been asked and answered many times.

Is this a single server? Wasthe proxy installed before the upgrade? Details of the correct ports and their settings can be found in this document: https://wiki.zimbra.com/wiki/Enabling_Z ... _memcached

I do not really understand the discussion in that thread.

Can modify something now to verify and/or fix this issue?
Can something be checked before update to not trigger this problem?

This feels like a show-stopper for upgrads, or is it only affecting some configurations/systems?

Some additional findings:

If I access the webmail by the hostname it works, but if I access by the generic alias I get the empty response:

postoffice.bxxxol.se => OK
mail.bxxxol.se => FAIL

postoffice.bxxxol.se is the fqdn of the server.
mail.bxxxol.se is a DNS alias to postoffice.bxxxol.se (CNAME)

This "name setup" has worked for years and many updates before.

This didn't affect the two installs that I've done here. You should confirm that it actually is that bug that's affecting you, details are in that report and a fix, specifically comment 6, you should be able to fix it with that: https://bugzilla.zimbra.com/show_bug.cgi?id=108299

OK, the problem most likely rise when hostname is not the same as the name used to access the webmail (very common scenario I guess. somehost.domain.com vs mail.domain.com).

This solved it for me:

Code: Select all

$ zmprov md bxxxol.se zimbraVirtualHostname mail.bxxxol.se zimbraVirtualIPAddress 192.168.1.12
$ libexec/zmproxyconfgen
$ zmproxyctl restart

But I really think this should be investigated further and fixed. Many upgrades to 8.8 will fail if this is the case...

[MisterM75]

I confirm that it is right, you have to add the hostname, CNAME among others or subdomain to IP for it to work, it's crazy, because before or can point any subdomain or domain on ip is it works ...

doing the upgrade from 8.7.11 FOSS (Centos 7.3) to 8.8.4 the problem is still there
