Dear Boris,
Unfortunately, our Nextcloud instance is no longer accessible via the browser following the recent update; however, the synchronization applications on our PCs continue to function correctly. I have forwarded the log file to you and would be most grateful if you could investigate the cause of this issue.
Many thanks,
Rudy
