Access to my ubuntu server with a public ip address-CodePudding

I have a problem with my raspberry pi 4 model B 4Go I have installed Ubuntu Server 21.10 And installed apache2 And I have a basic ssh access I can access it (ssh and web) with its local ip (192.168.1.90) However impossible to connect or to load a web page with its public ip address, firewall of my pc all closed. I don't understand the problem because before on my computer with Wamp installed, lowering the firewall and loading an apache page with a public ip was totally possible (by retesting just now it works without any problem) I also opened port 80 on my box for testing and still nothing

Is there anything else to configure on my box or directly on my server? Thanks

<Directory />
      Options FollowSymLinks
      AllowOverride None
      Require all denied
</Directory>

<Directory /usr/share>
      AllowOverride None
      Require all granted
</Directory>

<Directory /var/www/>
      Options Indexes FollowSymLinks
      AllowOverride None
      Require all granted
</Directory>

#<Directory /srv/>
#     Options Indexes FollowSymLinks
#     AllowOverride None
#     Require all granted
#</Directory>

Here the part of the content in etc/apache/apache2.conf but I don't think it's that since I can't connect anywhere with this ip

The apache configuration is correct. Can you check and upload the /var/log/apache2/error.log file of apache to check what is the error? Run the tail -f command on the log and refresh the web by accessing the public IP.

It is possible that your router is blocking the traffic. Have you opened the ports?

I managed to complete my problem thanks to the "port forwarding" option on my box and not the firewall, it is enough to redirect the ports 80 to its local ip, I did not know at all that this option existed. It is possible to do it with all ports. The firewall doesn't seem to influence this, thanks to you
