Modern UI is not accessible
Modern UI is not accessible
Problem
Modern UI is not accessible directly or its fall back to classic UI when clicking on Modern Web App.
Solution
Following are the possible solutions to fix this issue.
Scenario 1
Try to reinstall "zimbra-timezone-data" package.
[RHEL/CentOS]
yum reinstall zimbra-timezone-data -y su - zimbra zmmailboxdctl restart
[Ubuntu]
apt install --reinstall zimbra-timezone-data su - zimbra zmmailboxdctl restart
If ModernUI is still not loading then collect the browser debug logs (https://web_client_url/?dev=1) along with server logs and share with Zimbra Support for furtehr troubleshooting.
- /opt/zimbra/log/mailbox.log
- /opt/zimbra/log/zmmailboxd.out
- latest install.log from /tmp/ [if available]
- latest zmsetup.log
- Output of "rpm -qa" or "dpkg -l"
Scenario 2
The value of an attribute zimbraFileUploadMaxSize can also cause this issue as Int cannot represent non 32-bit signed integer value "21474836480" while loading the modern UI.
Make the following changes :
su - zimbra zmprov ms `zmhostname` zimbraFileUploadMaxSize 21474836480
Now access the Modern UI.
Scenario 3
The partial upgrade can cause the issue. To verify it, check /opt/zimbra/log/zmsetup.date-time.log and /opt/zimbra/.install_history files.
