other than the spoke failed to connect to another spoke what is the next step in resolving the connection issue.
The outside of each spoke router can access the outside of the other spoke router.
this is a problem between these two sites each spoke router has connectivity between 90 other spoke routers on the same DMVPN network.

Hello,
difficult to say what the problem is. Are all 90 spokes configured in the same way ? Is there a difference in hardware/software ?

Also if you can disable /enable the affected spokes tunnel interface

Paul,
I am unable to restart/bounce most of the sites tunnels due to site activity. I found multiple sites with the same issue and was able to bounce two sets of the sites tunnels.
In one case this recovered the site to site connectivity between these two site.
But the second set of sites bouncing the tunnels did not recover the DMVPN connection between these two sites.
I also went through the spoke sites with the connection issue and removed the line "ip nhrp shortcut" from the tunnel configs.

So it sounds like you are using eigrp as the routing protocol, can you post the the run config of the tunnel interfaces from the NHS HUB and at least one of the NHC spoke.
