After restart dns doesent work anymore

I fixed SSL and dynamic ip succesfull. Right now i have another problem…I have static ip set it on my Ubuntu. I wana mention i`m running ubuntu 18.04 on virtual machine on Nas Synology (the ip was set manually). All the time when i restart the virtualmachine where webmin/virtualmin running my site doesent works anymore, seems my dns server its broken. If i delete the virtual server and i create it again start works…Any solution for this? i installed webmin/virtualmin with root. Another question my cname say WWW CNAME OK. No CNAME


Check, if after a reboot your configuration isn’t over written with cloud init script(s) and/or set as permanent at the first place. Check and compare outputs of ip a, after and before reboot.

What you’re facing is not Virtualmin issue.

Yes, after 2h or 3h i found a thing i made in dns records. i just add an www with cname , because intodns tells me i dont have cname. and from there i get errors on bind dns server and stoped working. right now i delete that record and works like a charm, thanks a lot for your reply. still i get this thing
WWW CNAME OK. No CNAME. i have an A record with www, and seems its working via web, so i dont need anymore cname for www. im a little new with webmin/virtualmin, but seems working very good. i have 3 things with yellow on intodns, like :
Different subnets WARNING: Not all of your nameservers are in different subnets
Different autonomous systems WARNING: Single point of failure
SOA Serial Your SOA serial number is: 1586957912 . This can be ok if you know what you are doing.
But are just with yellow and other stuffs works very good. Thanks again for your reply
