I have a cyberpannel installation that works great on Vultr throught Cloudflare and all the DNS and RDNS are already configured. I am able to send and recieve emails from Rainloop so I guess that everything is fine on this side.
The only problem is when I try to configure Rainloop in order to send and recieve emails from Gmail. Actually, I tried to follow this tuto (How to Configure an Email Client for Rainloop (SMTP, IMAP, POP settings for Gmail) - YouTube) which is very good but unfortunately when I hit “test” in order to try the 993 and 465 ports I got an error :
So I tried to deactivate the firewall as you can see : firewall — ImgBB
Because I thought that it was causing the issue, but unfortunately I got the same error again.
Do you think that I did something wrong?
Thank you for your help.
