Have you used letsencrypt ? If yes there is already a redirection in /etc/nginx/conf.d/forcessl-yourdomain.tld without www. Just add the www and remove your other redirection
You’re a life savior. Everything works
However should I keep my two A records ? (One just the domain pointing to server IP and www.domain.com pointing to the same server IP)
And any idea for my mail server problem ?
yes keep your two records.
No idea for the mail server
I’m 100% sure I forgot a step or there is more things to configure to get the mail server working.
Can you give me a detailed step by step installation process ? With the dns configurations ?
If you don’t have time it’s fine but I would be infinitely grateful.
Thanks in advance
