We had the same problem when upgrading Carbonio-CE 25.6.0 to 25.12.0 - all packages upgraded without major issues, pending setups -a run, modules restarted via zmcontrol and even the entire server rebooted. Webmail works just fine, e-mails are sent and received, just :6071 ends with "Something went wrong".
I've wasted invested some time into investigation so I can share my suspisions - I believe problem is related to the switch from carbonio-admin-ui to carbonio-admin-console-ui that happened somewhere between 25.6.0 and 25.12.0. Ubuntu package system handles the package conflicts pretty well and allows to only one of those to be installed, HOWEVER:
the fact that problem can be relieved by switching the entire admin/ contents with the ones from older Carbonio installation makes me believe that it is the contents of /opt/zextras/admin/iris/components.json that are incorrectly migrated to serve carbonio-admin-console-ui and a migration procedure to adjust the contents of this file to match the installed packages should be provided.
In fact, there are quite a few problems in any version above and in 25.9. Servers with previous versions run very well, and I don't intend to update, as it's been 6 months of the same problems and new ones appearing in each new version.
@carloscunha
I would suggest you to apply the hotfix 26.3.1 that fixes the admin UI issues or may be a new installation to check the current status.
I will only update after months of release and with complete certainty that there are no new or old problems returning. Unfortunately, my confidence in the product has been lost, and in fact, if there isn't a real reason to update, I won't...
In versions prior to 25.9, everything was very good.
I ended up migrating new installations to Zimbra Maldua and so far everything is ok, and in the future I intend to migrate the installations I have from Carbonio as well.
I know problems happen in any product, but how we deal with them makes a difference.
I did a fresh install (not an upgrade) to test the latest version on Ubuntu 24.04 and I'm having the same problem in both Webmail and AdminWeb: "Something went wrong"...

Hi,
That's strange. I did a test few minutes back and everything was fine.
I would really like to understand what is happening in your case.
Please feel free to suggest what we could do.
Thanks

I honestly don't know how to solve these problems, but today I can't even install Carbonio without encountering the error message.
The last test follows this pattern:
- VirtualBox VM
- Ubuntu 24.04
- DNSMASQ configuration (for simple and fast DNS resolution on the test domain)
- Apt update and upgrade
- Download the installation script
- Run the script
- Currently, there are no errors in this process (unlike before when it wouldn't even finish)
- However, the same error always occurs since the last 3 versions, webmail and web admin access errors.
NOTE: Since every comment I make requires moderation approval, and this takes a long time or isn't even approved, it's difficult to help in any way.
Hi,
The simillar issue i have faced, fresh installation of Carbonio CE went well but after reboot panel stopped working. ERR_CONNECTION_REFUSED. i did not understand why is this happen? Please suggest how to get rid of these error.
Thanks
