I have a pivpn on a pi & a mesh system(192.168.5.1) connected to the
isp's router(192.168.0.1). My server is connected to the mesh, is
there a way I connect to my server via the pivpn... isp router and
mesh have different ssid & operate different lan ip ranges... image
may help.

First thing you need to do is eliminate the double nat situation you
have going on.

Is there a route between the two subnets (ie. device on the ISP router
can ping your server)? If there is, you should be able to put up an
SSH server on the VPN box, log into the VPN, and then from there SSH
into your server as normal. Look up "SSH jumpbox" or "jump server" for
more info on this sort of usage.

If there isn't a route between the two subnets, you should still be
able to do this, you just might have to forward a port from your mesh
system to the server behind it, as if you were forwarding it to the
world - in this case you wouldn't be exposing anything to the wider
internet, since "WAN" is just your ISP router's LAN. You'll then be
able to SSH in using the mesh system's IP address in 192.168.0.0/24
rather than the server's address on 192.168.5.0/24. It's a bit of a
hacky fix, but I've had to do similar due to being stuck with a ISP
router that I can't put into bridge mode.

I also have a mesh system, and I recommend that you change the mode on
your mesh from Router to AP, just do a quick Google search like" {mesh
system name} access point mode" or something like that...makes life a
whole lot simpler
