Hi everyone, I have been using mailcow selfhosted for about 3 years. So far everything has worked without problems, only after the last update on July 13th. I get "no mailbox selected" when I log into SOGo. Before that, the last time was on July 6th. `update.sh` executed. [Unfortunately, other discussions didn't work for me.](https://community.mailcow.email/d/23-mailcow-on-aws-no-mailbox-selected) I hope you can help me here. If someone needs further information / logs, please let me know.

Oh, yes, I forget the `source mailcow.conf` part in front of the command, sorry. Try to login as mailbox user and reset the EAS cache.

Hi, Please try this (run from within the mailcow folder): ``` source mailcow.conf MAILCOW_BRIDGE=$(docker-compose config | grep -i com.docker.network.bridge.name | cut -d':' -f2) while read NAT_ID; do iptables -t nat -D POSTROUTING $NAT_ID done <

The output of `ip6tables -L -vn -t nat` would be great, too. :)

Hi diekuh! Thank you for the fast answer. ip6tables is attached: [upl-file uuid=f384f5f8-d558-44d8-bd98-19d4227d795d size=6kB]ip6tables.txt[/upl-file] When I execute your commands the following error message appears: `Usage: grep [OPTION]... PATTERN [FILE]... `. The variable `$IPV4_NETWORK` was empty, according to mailcow.conf it is `172.22.1`. So I executed the commands one after the other and lo and behold: it works, SOGo finds the mailboxes again! Only the synchronization with the active sync devices like smartphone does not work yet, do you have an idea or tip here? In the log I find nothing noticeable, except for the errors with current source cannot synchronize defaults: ``` sogo-mailcow_1 | Jul 15 18:47:59 46169aa8b950 sogod [70]: [ERROR] current source cannot synchronize defaults sogo-mailcow_1 | Jul 15 18:47:59 46169aa8b950 sogod [70]: [ERROR] current source cannot synchronize defaults sogo-mailcow_1 | Jul 15 18:47:59 46169aa8b950 sogod [70]: SOGoUserHomePage user 'christian@allround-sounds.de' logged off sogo-mailcow_1 | Jul 15 18:47:59 46169aa8b950 sogod [70]: 217.253.81.128 "GET /SOGo/so/christian@allround-sounds.de/logoff HTTP/1.0" 302 0/0 0.091 - - 0 - 12 sogo-mailcow_1 | Jul 15 18:47:59 46169aa8b950 sogod [70]: 217.253.81.128 "GET /SOGo/so/ HTTP/1.0" 200 9252/0 0.032 30518 69% 0 - 12 sogo-mailcow_1 | Jul 15 18:48:01 46169aa8b950 cron[10]: (*system*sogo) RELOAD (/etc/cron.d/sogo) sogo-mailcow_1 | Jul 15 18:48:02 46169aa8b950 CRON[79]: pam_unix(cron:session): session opened for user sogo by (uid=0) sogo-mailcow_1 | Jul 15 18:48:02 46169aa8b950 CRON[78]: pam_unix(cron:session): session opened for user sogo by (uid=0) sogo-mailcow_1 | Jul 15 18:48:02 46169aa8b950 CRON[80]: (sogo) CMD ( /usr/sbin/sogo-tool expire-sessions 480) sogo-mailcow_1 | Jul 15 18:48:02 46169aa8b950 CRON[81]: (sogo) CMD ( /usr/sbin/sogo-ealarms-notify -p /etc/sogo/sieve.creds 2>/dev/null) sogo-mailcow_1 | Jul 15 18:48:03 46169aa8b950 CRON[78]: pam_unix(cron:session): session closed for user sogo sogo-mailcow_1 | Jul 15 18:48:03 46169aa8b950 CRON[79]: pam_unix(cron:session): session closed for user sogo sogo-mailcow_1 | Jul 15 18:48:27 46169aa8b950 sogod [74]: Sleeping 45 seconds while detecting changes for user christian@familie-hesseling.de in Ping... sogo-mailcow_1 | Jul 15 18:48:42 46169aa8b950 sogod [11]: [WARN] pid 74 has been hanging in the same request for 1 minutes sogo-mailcow_1 | Jul 15 18:49:01 46169aa8b950 CRON[87]: pam_unix(cron:session): session opened for user sogo by (uid=0) sogo-mailcow_1 | Jul 15 18:49:01 46169aa8b950 CRON[88]: (sogo) CMD ( /usr/sbin/sogo-tool expire-sessions 480) sogo-mailcow_1 | Jul 15 18:49:02 46169aa8b950 CRON[91]: pam_unix(cron:session): session opened for user sogo by (uid=0) sogo-mailcow_1 | Jul 15 18:49:02 46169aa8b950 CRON[92]: (sogo) CMD ( /usr/sbin/sogo-ealarms-notify -p /etc/sogo/sieve.creds 2>/dev/null) sogo-mailcow_1 | Jul 15 18:49:02 46169aa8b950 CRON[91]: pam_unix(cron:session): session closed for user sogo sogo-mailcow_1 | Jul 15 18:49:02 46169aa8b950 CRON[87]: pam_unix(cron:session): session closed for user sogo sogo-mailcow_1 | Jul 15 18:49:13 46169aa8b950 sogod [74]: Sleeping 45 seconds while detecting changes for user christian@familie-hesseling.de in Ping... ```

I deleted the EAS cache, and after 1-2 hours the smartphones started to synchronize the emails. Thank you so much! @"diekuh"#p1045

Hi @"diekuh"#11, I hope you can help me with another problem related to this. After I have executed your commands (I have to execute them every time the server is restarted), other docker containers from other networks (like 172.19.x.y) on the same host cannot send emails to the email server. $HOSTNAME is used as smtp host. SMTP Error: Could not connect to SMTP host. It looks like after your commands above, no connection can be made from other docker networks.

Alright, now everything works! certdumper did not work propertly, so no certificates were copied from traefik and the certificate had expired a few days ago.

@"chesseling"#p1046 can you help inform me how to delete EAS cache, i just restore from mailcow backup to other server and now i am facing no mailbox selected 😓 thanks

@"jtdoank"#p4568 Log in at Mailcow as an mailbox user (not at SOGo), under Mailbox -> Settings click on Reset Active Sync Device Cache -> Reset Now. But that doesn't sound like the problem that the EAS cache could solve. Are the accounts with the mailboxes still in Mailcow? You only see the error in SOGo?

@"chesseling"#p4577 Hi so sorry late reply, already reset but still no result Yes, the account still on the mailcow and even the message also still count as it is also Yes the error is only on SOGo but its seems the dovecot problem did anyone ever facing this problem?

SOGo "no mailbox selected"
