Configuring DNS & TLS

Based off the root DNS zone set in EE Site Configuration (e.g. stackblitz.example.com) set the following DNS A records to point at your instance's IP (172.16.4.20 in this example):

A stackblitz.example.com 172.16.4.20
A *.stackblitz.example.com 172.16.4.20
A *.preview.stackblitz.example.com 172.16.4.20

TLS

For TLS, your certificate should have stackblitz.example.com as the Common Name (CN), and the following Subject Alternative Name (SAN's):

  • stackblitz.example.com
  • *.stackblitz.example.com
  • *.preview.stackblitz.example.com
