Can someone please explain, why nginx complains or where to review logs? Am new to snap. Any other suggestions also welcome? No Apache or Nginx running

Answer 1

I solved the same problem but with microstack.ovs.vswitchd

To solve the problem I had to install openvswitch-switch-dpdk.

Your solution may be to install nginx or reinstall it..

Answer 2

I encountered the same problem, I tried to check if apache2 was running on the same port but in my ubuntu-ec2 instance, I haven't installed apache2 so technically I shouldn't have this error.

So, I look for if any other service was running using the network tools

Then I found out that the datadog-agent service was using the same port, I removed the service and then tried to initialize microstack using microstack init --auto --control and it worked. After the microstack was up and running, I then installed a datadog-agent to monitor my ec2 instance.

If you still have this error, look for ports using the network tools and try to remove those services and re-install after you initialize the microstack.

My Ec2 Details:

Ubuntu server 20.04 LTS

RAM: 8GB

Storage: 20Gb

VCPU: 2
