Google Cloud Compute Engine open ports?

Question

Google Cloud Platform

I ask for help, I created a BM machine, I go as in the description - a firewall - I create tcp 80 and tcp 443, i.e. I open ports of course. I change the target tag on the BM machine - I specify the new rules created in the brandmauer - ok. I reboot the machine - ports are closed. Ok, let's move on, the system was installed by ubeuntu 16.04 TLS - we go to iptables - we ask for ports 80 and 443 - to which the ports are open ... Again I check port 80 - externally closed ... Ip issued static both internal and external for cars.
If I put, for example, a package ready for WP - then all the rules that I created work fine there - and all the ports that are required are open.
But with the machines there is a problem, with empty ones, tell me, maybe I'm doing something wrong?
search unfortunately did not give an answer to my question, the second day has already gone - this issue is not solved in any way ...

Answer 1

The same question.
UPD: In general, after several hours of searching, I finally figured out this issue. In Google Cloud, due to their focus on their control panel, the local IP is not 127.0.0.1, but 0.0.0.0.
I launched the software on IP 0.0.0.0 and it all worked. Oh, and I had to dig deeper :))
