I am contacting you because I can't get mercure to work in production.
The binary prebuild runs fine, but when I try to connect to the hub, I get a 404 no found.
Here is the command I run :
sudo MERCURE_PUBLISHER_JWT_KEY='eyJhbGciOiJIUzI1NiIsInR5cCI6...' MERCURE_SUBSCRIBER_JWT_KEY='eyJhbGciOiJIUzI1NiIsInR5cCI6...' SERVER_NAME=:3000 ./mercure run
the server launches without any problem apparently:

When I try to access the hub with postman by typing the following command:
https://monsite.com/.well-known/mercure
I get a 404 no found.
I am under linux debian 10 with apache2. I don't understand what I did wrong. Thanks for your help.
EDIT 21/02/2022
Hi Mehmet, here is what I did:
In /etc/apache2/sites-available monsite.conf and monsite-le-ssl.conf :
ProxyPass /mercure-hub http://localhost:8080/
ProxyPassReverse /mercure-hub http://localhost:8080/
In Caddyfile and Caddyfile.dev :
{
{$GLOBAL_OPTIONS}
auto_https off }
{$SERVER_NAME::8080}
Apparently the hub launches well, I have no error in the console:

Whether I run Caddyfile or Caddyfile.dev, when accessing https://monsite.com/mercure-hub, I get a 500 error.
After some digging, I tried to figure out why it was returning a 500 error. I went to the apache logs, I had this error message:
"No protocol handler was valid for the URL /. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule"
So I installed the missing components:
sudo a2enmod ssl
sudo a2enmod proxy
sudo a2enmod proxy_balancer
sudo a2enmod proxy_http
I also modified the proxy urls by adding a slash at the end of mercure-hub, otherwise I would get a 404 error:
ProxyPass /mercure-hub/ http://localhost:8080/
ProxyPassReverse /mercure-hub/ http://localhost:8080/
Restarted apache, and updated the Url in my .env :
MERCURE_URL=https://monsite.com/mercure-hub/.well-known/mercure
MERCURE_PUBLIC_URL=https://monsite.com/mercure-hub/.well-known/mercure
And it works, thanks a lot !
