Original GitHub issue: https://github.com/amidaware/tacticalrmm/issues/1372

Server Info (please complete the following information):

OS: Ubuntu 20.04.1
Browser: Microsoft Edge
RMM Version (as shown in top left of web UI): 0.15.5

Installation Method:

Standard
Docker

Agent Info (please complete the following information):

Agent version (as shown in the 'Summary' tab of the agent from web UI): v2.4.3
Agent OS: [e.g. Win 10 v2004, Server 2012 R2]: Windows 10 22H2

Describe the bug
I get this error whenever I try to install the agent on multiple different PCs outside of my LAN:

Get: "https://xxxxxxxxxx.com/api/v3/installer/": context deadline exceeded (Client.Timeout exceeded while awaiting headers)

It only started happening recently, I previously had no problems installing the agent. Google hasn't given me much info on this error or why it may be happening. It also doesn't work regardless of using manual installation/powershell/dynamic exe

To Reproduce
Steps to reproduce the behavior:

Attempt to install agent on PC external to network

Expected behavior
Normal agent installation

Screenshots

Additional context
I've tried restarting the RMM server and the PC hosting it, rebooting client machines, changing DNS settings, generating new .exes, nothing seems to fix it
