[SOLVED] Need Help! Cannot access web interface after accidentally installing on the host

[thorleif]

Hi,

I messed up by accidentally trying to install Pterodactyl (https://pterodactyl.io/panel/1.0/getting_started.html) on the PVE host rather than an LXC that I had created. The installer tries to do some NGINX business and also makes changes to the UFW firewall. Now my PVE host is still running fine with all virtualization intact but I cannot access the web interface on https://192.168.1.100:8006/. Not sure how I could go about fixing this. I have PBS running but only for the LXCs. AFAIK backing up the host itself is not yet possible. Any help would be much appreciated.

Some terminal output on PVE:

root@pve:~# systemctl status pveproxy.service

and so on... It gets the login page.

Some terminal output on a different machine:

I found that UFW had been installed and was blocking port 8006, so I got it working again by uninstalling UWF. I also ran

iptables -F
iptables -X

in an effort to get rid of any possible `iptables` rules that UFW might have left behind. I hope that didn't purge any important default settings in PVE.
