  1. IPv6 must be disabled. Make also sure that the /etc/hosts does not contain any IPv6 entries.

once i disabled IPV6 and restarted carbonio it worked like a charm!

Fixing:

Edit /etc/sysctl.conf

add this two lines below and save it:

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

Run "sysctl -p"

Then, retstart Carbonio: zmprov restart

 

You, sir saved me a lot of headache... I wonder why the devs did not respond to this! Hope, I have not overseen something....

 

Fresh Install @ Ubuntu 

Carbonio 23.7.4

Error in nginx.log is as follows:

Any idea how to investigate and resolve would be appreciated.

2023/06/17 21:07:39 3173#3173: *687 open() "/opt/zextras/admin/login/i18n/en-US.json" failed (2: No such file or directory), client: myip, server: , request: "GET
/static/login/i18n/en-US.json HTTP/1.1", host: "myhost.com:6071", referrer: "https://myhost.com:6071/static/login/"

in fact the file en-us.json doesn't exists.... the one there is en_US.json, so I copy it to the right name and that erro disappear... sadly it doesn't fix the main issue above.

=(

Carbonio Release 23.5.0

Error: "JSON.parse: unexpected character at line 1 column 1 of the JSON data"

when I try to log in on port 6071, but I can login as regular user on the webmail.

Looking into console erros I found this:

POST https://myserver.com:6071/service/admin/soap/AuthRequest

This is a fresh install.

Looking in nginx.log I also found this: "no live upstreams while connecting to upstream"

 
May you help me to figure this out?

(JSON.parse: unexpected character at line 1 column 1 of the JSON data)
When I tried version 22 it worked correctly, after installing v23, I have this problem and the Zextras Mail apk does not connect to my server.
What should I check to fix this error?

1457806#1457806: *285117 no live upstreams while connecting to upstream, client: 1.1.1.1, server: , request: "POST /service/admin/soap/GetMailboxRequest HTTP/1.1", host: "mail.example.com:6071", referrer: "https://mail.example.com:6071/carbonioAdmin/manage/domains/803ddd6f-eaff-45ce-89cb-c45fb8fa71a4/accounts"

is like the connection internal between the nginx and the 7071 admin console of zimbraAdmin fail or was lost for timeout,

from firefox console I found it happens most than all with the POST:

POSThttps://mail.example.com:6071/service/admin/soap/GetSessionsRequest
