@anton6 I increased all the resources for Docker. Although inconsistent, it works for localhost:3000. I am also unable to access localhost:4000 as yourself. Do you have any good news on this by any chance?
Thank you @DominguesGM. I applied those steps just now
I increased Docker's resources to 6 CPUs, 7 GiB memory and 2.5 Swap. I was just about to complain about the ports not responding on the browser again until I realized that they respond after a long delay
@machikoyasuda your suggestion worked for me, thank you
