/etc/cron.daily/trim-txrep:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
Unfortunately, since then emails are not sent to Office 365 to the destination server: princ-cz.mail.protection.outlook.com
Emails remain in the outgoing queue with an explanation:
(Host or domain name not found. Name service error for name=princ-cz.mail.protection.outlook.com type=A: Host not found, try again)
I've tried via shell nslookup to different servers, also ping and all of them work except for the server mentioned above.
It was working without problems until yesterday.
Where could be the problem that only this DNS entry can't be forwarded/translated??
In /etc/resolv.conf I have:
Code: Select all
nameserver 127.0.0.1
Code: Select all
dns_available yes
dns_server 127.0.0.1
Code: Select all
forward-zone:
name: "."
forward-addr: 193.17.47.1 # First DNS Server
forward-addr: 185.43.135.1 # Second DNS Server
forward-first: yes
Code: Select all
nmcli con mod ens192 ipv4.dns "127.0.0.1"
nmcli con mod ens192 ipv4.ignore-auto-dns yes
nmcli con down ens192
nmcli con up ens192
Thanks for any help.
