📝 Provide a clear and concise description of the issue.

Hello, I have Proxmox v8.4.1 running and I have been having issues trying to install Flaresolverr (as well as several other LXCs). I should say that they install just fine, but then I cannot connect to them through a browser. However, I'm able to ping the IP address of the LXC, and from within the LXC shell I'm able to ping addresses on the internet. I feel like it has something to do with the ports being blocked, but I'm not sure how/why they are blocked.

I am running a UDM Pro for my router with Unifi Network 9.1.120. I have quite a few firewalls rules up, but I don't see one blocking ports. In fact, I just checked my firewall rules, and I don't see any that are blocking ports (except my camera network), only allowing specific ports to specific networks.

🔄 Steps to reproduce the issue.

1. Install Flaresolverr using the Community Script command
2. Try to login to the web UI through a browser, connection refused.

❌ Paste the full error output (if available).

This site can’t be reached
10.69.20.23 refused to connect.
Try:

Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_REFUSED

🖼️ Additional context (optional).

Let me know what additional information I need to provide.

And service is running? Systemctl Output?

Yes, the service is running. See below.

root@flaresolverr:~# systemctl

Looks strange, can you share an full Screenshot of systemctl flare... And maybe the journalctl?

Hopefully this is what you meant, let me know if you need something additional. I'm pretty new to Linux in general, FYI.

root@flaresolverr:~# journalctl -u flaresolverr > flaresolverr.log

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.
105 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

Is your proxmox a standalone node? from https://github.com/FlareSolverr/FlareSolverr, the default port appears to be 8191

Are you able to make calls against that port?

[larsony99]

It must have been something weird with the WiFi I was on when I tried it; Delta must have blocked some of those ports and I couldn't get around it.

Got home, reran the script and it works just fine now.

I am running into the same issue; tried deleting the lxc and rerunning the script but same thing happens, unable to connect

The latest release is a docker deployment release only, but our script has no way of knowing that. Please wait for the next release to try and installing.
