Hey guys, been stuck on this for over a week. I’ve read all of the relevant topics on meta and tried all the solutions here and elsewhere and nothing’s working. I’m just stumped.
Every time I try to `./launcher rebuild app` it goes all the way to the end and then…

```
Thinking the solution has got to be easy, but can’t find it.
Anybody know the answer?

Something is clogging up port 80, which means webserver of some kind.

Thanks Jeff, read your comment on a thread about this from '15 earlier today. Is there a terminal command to trace what’s using it?

Tried `sudo lsof -i :80` and got.

Okay, I was doing it wrong. Exited `root` and hit `sudo lsof -i :80` again. Still trying to figure out what this is, but it’s progress.

Thoroughly confused now. Used **Activity Monitor** and sorted by Port. A `Google Drive File Stream` app I just downloaded was built to take port 80. App was wack so it gets the full delete and empty the trash. As soon as I shut down the Google App, something called `ContactAccountsServices` shows up in **Activity Manitor**. I shut it down and run a full computer restart.
Computer starts again. I discovered what `Google` above is two tabs in Chrome. Shut down Chrome and run `./launcher rebuild app`. After restart I go `ssh root@...` and ran `system reboot` on the Ubuntu server. That seemed to do something but you never want to get too excited. So I go back and long story short

So, yeah. I’m ready to get out grass skirts and chicken bones to debug this. It’s some Voodoo that’s got to be some simple thing I’m staring right at but have not tried. What that is, I cannot tell you. Can you tell me? Please? My sanity hangs in the balance. I’m better than this. lol

Removed the nginx welcome page, but now nothing loads — [https://bitkcor.com/](https://bitkcor.com/)

Still staring at a blank page. Do I need to restart something now? Any suggestions?

Actually. Just set the SSL back to strict in Cloudflare and it brought it all back.
`sudo systemctl stop nginx` was the answer.
Thank you @riking!
