the problem is your ssl certificate

I assume you used certbot to get the ssl certification?

force rerun certbot and see if it helps

if not then its time to go thorugh your external webserver config

[raw reef]

Is there an SSL certificate at all?

[toxic junco]

good question

if they only enabled force https without ssl certificate that would explain the question aswell

nvm

they didn'T enable force

I can access it via http

I can access the map with safari on my iphone with no issues

[marble shale]

i’m gonna be real idk what an ssl certificate is

[toxic junco]

It is the thing which allows you to put the "s" at the http so with ssl certificate it is https

are you the server admin / dev?

[marble shale]

yeah i’m the admin

I will take advantage of your issue to learn wether there is another way to do this, but I will tell you what I have in case it may help

The setup I find to be the cleanest and that I use is using Ngnix as a reverse proxy, this way I expose only port 443 and connections to my map don't include the ugly :8123 port.

Port 443 is the secure http port (which makes it https), and thus needs an ssl certificate to work, this certificate may be provided by your domain registrar; I use Cloudflare and I can generate certificates for my domain there.

Nginx is a web server, when put into reverse proxy mode, what it does is expose the port you like (443) and route all requests made to your dynmap's subdomain to the Dynmap application, which is hosted locally on port 8123

So if a user should search "play.coronacraft.cc", the request would enter port 443 to Nginx, which in turn would hand the request to Dynmap on port 8123 (you would specify this rule on Nginx, config)

[toxic junco]

(there is a very good step by step guide for this reverse proxy setup on the dynmap wiki)

I hope it is okay if I add some stuff

Optionally you could try to add a cloudfare ddoss protection in aswell, adding an additional layer of security.

I actually had no idea, thanks!

[toxic junco]

No problem, the wiki is a great wiki with very detailed explanations

[marble shale]
