Hi @nikolaik,

Good day!

Can you please guide?

Few months back I did not face this issue but now I am unable to build the application itself.

DNS lookup errors are most likely a result of a network issue outside the scope of this specific docker image.

Some things to try:

• Restart your docker daemon
• Restart your machine/VM
• Restart your network hardware
• Double check your macines' DNS configuration
• Disable/restart VPN
• Try running the build on another machine
• Try switching to another network

Good luck!
