Zimbra Forums

Hi,

I installed zimbra 8.7.10 and after the installation zimbra run normally but after I restart my zimbra error server like that :

HTTP ERROR 502

Problem accessing ZCS upstream server. Cannot connect to the ZCS upstream server. Connection is refused.
Possible reasons:

upstream server is unreachable
upstream server is currently being upgraded
upstream server is down
Please contact your ZCS administrator to fix the problem.

How to fix this error?

Thanks a lot.

Is this multi-server or single server installation?

Please send me an output of following commands? (they need to be run via zimbra user)

zmprov gs `zmhostname` zimbraReverseProxyMailMode
zmprov gs `zmhostname` zimbraMailMode

and check to find out any log messages related to this error in nginx.access.log and send to me.

Hi guys

I have the same problem with zimbra 8.7.1

I cannot reach ZImbra webmail.

I use only HTTPS and proxy mail is redirect, I really would not like to reconfigure my proxy mode because of multiple domains that I use

Can anyone help me ?

Thank you

This is single server and this is a ssd vps.

This is the output of following commands :
root@mail:~# su zimbra
zimbra@mail:/root$ zmprov gs `zmhostname` zimbraReverseProxyMailMode
# name mail.torreskonsultan.co.id
zimbraReverseProxyMailMode: both

zimbra@mail:/root$ zmprov gs `zmhostname` zimbraMailMode
# name mail.torreskonsultan.co.id
zimbraMailMode: https

And this is the output of nginx.access.log

Could you analyze that?

Hi all,

Thanks for your help.
This problem is fixed now. The problem is my server port 8443 is used by plesk and conflict with zimbra. I reinstall zimbra and chaged the port 8443 to 8445.

The answer to this problem is in this thread. I''m assuming you either haven't checked that or don't have the same problem - in either case, you should not add your post that's markes as solved and you should have started a new thread. You should also give sufficient inform,atio so people can give you some advice on a solution and you should also search the forums for an answer.

You can start by giving the full version of ZCS that's in use by posting the output of the following command (always post this when asking a question on these forums):
Is this a single serevr or a multi-server installation, is it a new install or an upgrade, what have you tried so far to fix the problem?

Hello. We have been through this problem with constancy so far we have not found a concrete solution.

If you can help us I will be immensely grateful.

Thank you very much in advance.

You should provide also mailbox.log and mailboxd.out

Good afternoon. My mailbox.log file is too large. Can I send you straight to your email box?
