Hello @vinayakb12,

A 504 Gateway Error is a timeout error so seems nginx is working but can’t connect to Apache. I suppose Apache is crashing or is stuck for whatever reason, high load, low resources, etc.

You must check your logs because there you should have more info about what is happening.

Check services:

systemctl status nginx
systemctl status apache2

Check journal logs:

journalctl --no-pager -eu nginx
journalctl --no-pager -eu apache2

Check error logs:



Hello there,
I just destroyed the server. on my new server, wget isn’t working
any way to fix?

Unable to establish SSL connection.
this is the error i am seeing

apt-get update && apt-get install ca-certificates

This also didn’t worked.
I am using OCI with a reserved IP

I tried downloading the hst-install.sh. and ubuntu version on other server and from that to new server.
Now, the hst-install.sh run gives error “Error: hst-install-ubuntu.sh download failed.”
