Hello,
I have a problem with version 1.0.0-beta.14. When I want to add a site under manage sites, I only have "local" as an option. I can't select "newt" or "wireguard".
The thing is, I’m not sure if I have the correct firewall configuration set up. The system is on a VPS where I have to manage the firewall myself, and they don't provide this for me. I’m attaching my iptables configuration. Could the problem be somewhere else?

@oschwartz10612 commented on GitHub (Feb 19, 2025):
We can definitely take a look at the firewall next but I think the initial issue is that Gerbil did not register with Pangolin so you do not have an "exit node" so you dont have the ability to create tunneled sites.
How did you install? Did you use the installer? If so there is a step that asks if you wanted to install gerbil and maybe you selected no?
Can you take a look at your docker compose file and see if gerbil is in there? If not you could add it manually or reinstall using the installer.
@urkosan commented on GitHub (Feb 19, 2025):
yes from installer. but then i did correction for Wildcard Config for DNS-01 Challenge

now is ok when i change to your config like tjis for gerbil:
block_size: 24
site_block_size: 30
subnet_group: 100.89.137.0/20
@urkosan commented on GitHub (Feb 19, 2025):
strange: when i restart vps the error is the same! I can not add new site only privius is working.

@urkosan commented on GitHub (Feb 19, 2025):
As soon as I enabled the proxy on Cloudflare, it stopped working. When I switched back to DNS only, it started working again.
Hmm: is ok to have ssl:full or i must have ssl:Full (Strict)
@miloschwartz commented on GitHub (Feb 19, 2025):
I can only confirm that Full (Strict) works because that is what we have done in our testing. It's likely that the other methods could work, I just haven't tested them all myself with Cloudflare. Try it out and let us know if it works for you! :)
@oschwartz10612 commented on GitHub (Feb 19, 2025):
Okay so are you able to use the newt connection now? If so my guess was it was having trouble registering with your previous settings.
@natemergler commented on GitHub (Feb 25, 2025):
i can also confirm this will only work with full (strict). it would be nice for this to be extra emphasized in the documentation.
sidenote: i plan on doing further testing to determine if this is something that could be configured to not be required. i suspect it may be because pangolin is https by default
