Admin URL going to wrong install

I’ve set up a second Ghost instance in a DO droplet.

The public URLs are resolving correctly, but both /ghost/ admin URLs are directed to the second domain URL. So the public domain firstinstall.com resolves correctly, but firstinstall.com/ghost resolves to secondinstall.com/ghost.

Inside the respective config.production.json files both of the admin > url parameters are set to their respective domains.

Any ideas? Thanks for your help.

Weird… I don’t really know what the problem or fix was, but here are some things to consider:

Again, I’m not really sure what the cause or fix was, but everything is sorted out now.
