Thank you, email sent.

I am using Outlook 2016, so I do not think it is the issue. Besides it also concerns clients running on a Samsung phone.

Hello, Unfortunatelly the problem is back again. No changes were made, no updates installed. Now the mailbox.log is full of this: 2024-03-09 08:54:50,875 INFO [qtp758013696-596:https://zimbramail/service/soap/] [name=address1@zimbramail;mid=3;ip=zimbramail_ip;port=60230;ua=Android-SAMSUNG-SM-J330F/101.9(...86a108) devip=84.137.243.12 ZPZB/71.4;soapId=116836f3;] soap - DestroyWaitSetRequest elapsed=2 2024-03-09 08:54:50,875 INFO [qtp758013696-601:https://zimbramail/service/soap/] [name=address2@zimbramail;mid=7;ip=zimbramail_ip;port=60256;ua=Android-SAMSUNG-SM-J330F/101.9(...86a108)...

Hello, By me it was solved with bug 101. Thank you!

Thank you. Or can it be that there is something missing on the zimbra server? nginx? The netstat shows this: root@mail:~# netstat -atpn | grep -iE '80|443' tcp 0 0 127.0.0.1:80 0.0.0.0: LISTEN 1712522/java tcp 0 0 0.0.0.0:443 0.0.0.0: LISTEN 1712522/java tcp 0 0 127.0.0.1:7171 0.0.0.0: LISTEN 1108086/java tcp 0 0 192.168.xxx.xxx:389 192.168.xxx.xxx:60380 ESTABLISHED 961/slapd tcp 0 0 192.168.xxx.xxx:54574 192.168.xxx.xxx:389 ESTABLISHED 1108086/java tcp 0 0 192.168.xxx.xxx:54804 192.168.xxx.xxx:389...
