Zabbix Server LDAPS Authentication

[flunda]

We changed our Zabbix Server from plain LDAP to LDAPS authentication against our Domain Controller. Zabbix itself works perfectly, nothing else changed.

The problem is that the Zabbix Vue Firefox Plugin sometimes changes to black and seems to lose the connection, but when we click on the black icon, we can still see the current Zabbix Issues, the Icon just turns to black as it would lose it's connection to the Zabbix Server. Then after some seconds it gets back to normal, e.g. to Green or Orange. The time the icon stays black differs, sometimes it's just 4-5 seconds, sometimes it's about 20 seconds, then it gets back to normal.

While we had zabbix server using plain LDAP the Plugin worked perfectly.

Firefox: 93.0
Zabbix Vue Plugin: 2.0.1
Zabbix Server: 5.4.6

Attached a screenshot.

thanks

followup: We have updated our zabbix-server to 5.4.7 and it is now working again.
