I can't seem to SSH into my server over VPN and can't figure out why. (kbin.social)

Using JuiceSSH on my phone, I'm able to connect to my device without any problems when I'm on my home Wi-Fi. However, when off WiFi and connected to my VPN, the server doesn't connect. I'm still able to access the services it's running, but can't SSH into the server itself.

Edit: I thought I answered everyone's questions but I'm not seeing the answers so I'm posting the info here.

I get the below message and nothing happens. Then about 60 seconds later Juice gives a timeout error.

ssh_socket_connect: Nonblocking connection socket: 98 ssh_connect: Socket connecting , now waiting for the callbacks to work

I'm using the built in VPN service in my router. It uses the OpenVPN protocol.

Edit 2: Using the same VPN config file, I'm able to access the server using Putty on my laptop. So I'm wondering if it is a Juice specific issue.

It's been a while since I've used OpenVPN, but if I remember correctly when I had this issue I had to change "dev tun" to "dev tap". Ultimately the problem was that OpenVPN was assigning an ip on an unrouted subnet. I could access the internet, but not local devices.

Personally I switched to Wireguard. It's just so much easier to configure and add/manage devices. OpenVPN is way more powerful and configurable than I need.

I'm not especially attached to OpenVPN, it's just always worked for me to this point and is built into the router firmware. So I haven't needed to change
