I switched from Elastic to Mailgun, but there is something bugging with my 443 port. My site is not working and I received this message :
Check your networking configuration to see that connections to port 443 are allowed.
Where/how do I check this?
Itâs unrelated to mallgun.
My guess is that you have port 443 blocked by some Firewall.
I donât see port 443 when I run nestat -tulpn . I checked with DigitalOcean and Cloudflare and there is no firewallsâŚ
This is what I see :
Checking your domain name . . .
WARNING:: This server does not appear to be accessible at forum.lepeuplier.ca:443.
A connection to port 80 succeeds, however.
This suggests that your DNS settings are correct,
but something is keeping traffic to port 443 from getting to your server.
Check your networking configuration to see that connections to port 443 are allowed.
Google: âopen ports YOUR CLOUD SERVICEâ for information for resolving this problem.
You should probably answer ânâ at the next prompt and disable Letâs Encrypt.
This test might not work for all situations,
so if you can access Discourse at http://forum.lepeuplier.ca, you might try anyway.
Does this look right?
Hostname : forum.lepeuplier.ca
Email : francois@lepeuplier.ca
SMTP address : smtp.mailgun.org
SMTP port : 2525
SMTP username : postmaster@forum.lepeuplier.ca
SMTP password : password
Letâs Encrypt : francois@lepeuplier.ca
The script is trying to connect to itself with your domain name and failing.
I spent considerable time writing those words to explain the problem, if there is one. I donât really have any better explanation.
Does your domain name resolve directly to your server?
If you are using cloud flare then in pretty sure you canât use letâs encrypt. Like it says, you can try it if you want to.

I donât understand what you mean by thatâŚ
Weird because Letâs encrypt + Cloudflare was working with Elasticmail⌠I will give it a try with mailgun
Does your domain name resolve to your server or to cloud flare?
Again, this has absolutely nothing to do with mail delivery.
My guess is that the last time you ran the setup script was before you configured your domain to point to cloud flare.

My domain name resolve (point? ⌠sorry Iâm french) to cloudflare and after to DigitalOcean
Yes you are right.
So if I am using Cloudflare, it is not necessary to use letâs encrypt to have a ssl connection?
My server for my wordpress site is with Inmotion Hosting and I have a free SSL. But for my subdomain that use Discourse, I am with Digital ocean and it appears I donât have free SSL. But before all that, this is pointing through Cloudflare and I also have a free SSL (full certificate).
It is really confusingâŚ
Sorry I should talk through another topic, it is not related anymore to mailservice
Yes, you do. Discourse ships with free built-in SSL support (Letâs Encrypt). If you set it up using the setup script, SSL should work out of the box. So if you are using cloudflare just for the SSL, you can just turn off cloudflare.
