MEAN LightSail Instance Stopped Working After Changing to Static IP Adress

Question

HI Everyone,

I desperately need your help. I have a MEAN instance in LightSail, it has been working fine for many months. I have changed the public ip address to static public address and I start receiving 503 error message.
 I use third party domain and I have updated A records too.
I reboot, stop and start the instance many times but it did not work
Your response is really appreciated.

Answer

Hi There

Have you checked the logs on the web server.  See [Debug Apache Errors](https://docs.bitnami.com/aws/infrastructure/mean/troubleshooting/debug-errors-apache/) from the [MEAN packaged by Bitnami for AWS Cloud](https://docs.bitnami.com/aws/infrastructure/mean/) guide.
