# Troubleshooting issues on your own server

This is an incomplete list of issues people have run into
when installing TLJH on their own servers, and ways they
have fixed them.
Before trying any of them, also consider whether turning your machine on and off
and/or deleting the VM and starting over could solve the problem;
it has done so on a surprisingly high number of occasions!

## Outgoing HTTP proxy required

If your server is behind a firewall that requires a HTTP proxy to reach
the internet, run these commands before running the installer

```bash
export http_proxy=<your_proxy-server>
```

## HTTPS certificate interception

If your server is behind a firewall that intercepts HTTPS requests
and re-signs them, you might have to explicitly tell TLJH which
certificates to use.

```
export REQUESTS_CA_BUNDLE=</directory/with/your/ssl/certificates>
sudo npm config set cafile=</directory/with/your/ssl/certificates>
```
