after update to 9.1 synchrony service doesn't work anymore

Question

we got a cluster with two nodes

the update to the version 9,1 shown no critical errors

both node are avaiable, but the editing of sites doen't work because the synchrony-service is not working or is errorful

before the update on version 8.9.5 everything was fine, no problems

i found many sites and advises, but i dont't really know, what i have to do

does anybody know this behavior and got a tipp for me?

the only error is this

Line  895: 2024-10-15 10:04:56,937 ERROR [Caesium-1-2] [troubleshooting.healthcheck.concurrent.SupportHealthCheckProcess] lambda$getCompletedStatuses$0 Health check 'Synchrony-Konnektivität' failed with severity 'major': 'Synchrony läuft nicht.'

all other stuff is only warning and info

Hi @KfW Confluence Do you have any error messages in the logs? That would be my first place to look. /logs/atlassian-confluence.log /logs/atlassian-synchrony.log Once you have narrowed down what the log files tell you. This is a good troubleshooting guide. https://confluence.atlassian.com/doc/troubleshooting-collaborative-editing-858772087.html
