I use https://portmap.io/. This way I don't have to worry about port forwarding and can access my client from any WIFI hot spot.
Are you using no-ip? Try portmap.io. There are videos on YouTube to help you set it up.

How it works
You create VPN tunnel from your PC to our server using free OpenVPN software and define port forwarding rule to forward requests from Internet through our server to your local machine. It works even if you do not have a real IP address or your incoming traffic is blocked. You can forward HTTP traffic to your local web-server as well as any TCP or UDP traffic. If your web-server has virtual hosts configured, you can specify which one you are connecting to.

Just a test. Process of elimination. Use free account, it's what I still use for over a year.

It should work on your own pc and other. You have a other issue not sure what it can be.
Try cleaning your stacks
Reset Network TCP/IP stack
If your TCP/IP stack is corrupted it can be reseted with the following commands.

Windows XP:

  1. Search for Command Prompt > Run As Administrator
  2. netsh winsock reset
  3. netsh int ip reset
  4. ipconfig /flushdns
  5. Restart computer

Windows Vista, 7, 8, 10:

  1. Search for Command Prompt > Run As Administrator
  2. netsh winsock reset catalog
  3. netsh int ipv4 reset reset.log
  4. netsh int ipv6 reset reset.log
  5. Restart computer

I made a mistake should be:
build client:

port= 58487
Server listen port:
Make sure "server is listening for port 4782" the one you configured on portmap site

If still no connect do this:

Search for Command Prompt > Run As Administrator
netsh winsock reset catalog
netsh int ipv4 reset reset.log
netsh int ipv6 reset reset.log
Restart computer

And of course make sure OpenVPN is running and connected

Ok, so you reset all stacks and Rebooted computer and OpenVPN's tray icon is green meaning it's connected to portmap.io

When you go to your mappings rules page https://portmap.io/mappings you should see a check mark by your mappings rule. That confirms that OpenVPN is correctly connected. It wasn't connecting before but it is now. I also reset my stacks like three times but more then likely all issues was site related. I'm guessing you tried no-ip and did that work for you?

Other then using No-ip or portmap.io are the only two I've used. And that message you get "connected for remote access" sounds like the option for try icon is on when building Quasar client, just select "Unattended Mode" under "Basic Settings".

The only free Android Remote Admin tool I had any luck with is "Spy MAX v2.0"

Yeah but spy max is not compatible with android 10 or higher maybe in future.
Any keylogger that will work on android 10 or 11 if you know?
