syed3000 installed Discourse on Google Cloud VM following the official guide, but encountered issues accessing the forum via domain despite successful installation and DNS setup. Initial VMs (2 vCPUs, 4GB RAM) failed to respond, while a smaller VM (1 vCPU, 1.7GB RAM) worked unexpectedly. schleifer asked about firewall rules and network configuration, noting the need to allow HTTP/HTTPS traffic. P16 inquired about load balancer usage, mentioning their own successful setup without one. syed3000 confirmed no load balancer was used and shared that the working VM is now live at forum3.thegreatpakistan.com, asking about its expected load capacity. They noted the puzzling outcome where slower hardware succeeded while faster VMs failed, despite identical setup procedures syed3000.
Everything went perfectly and there were no error messages. And even the DNS mapping was done properly to my domain name, but after installation when I enter the domain name in my browser, it doesnt open anything and after a lot of waiting I receive an error message from my browser stating that the browser cannot open the page because the server where this page is located isn’t responding.
I have checked ping response to the server using my domain name and its pings perfectly, can you please guide me how to being with the troubleshooting process?
Yes, The VM is on the default network with properly configured rules to allow HTTPS traffic only. It was not working initially, but surprisingly on third VM it built successfully and is now working fine. The first two VMs had two VCPUs with 4GB Ram of Ram, and the third VM had only 1VCPU with 1.7GB Ram. I followed the same process on all three, but surprisingly only the third worked. Anyways, I have deleted the two previous VMs and only the last one is running now. Can you please let me know how much load can this server handle at the given time? https://forum3.thegreatpakistan.com
