ping fails to hosts behind the VPN router

We have site to site VPN. using IPSEC/GRE. Centralised headend with several remote sites. One of the remote sites is connected but when I ping 347 Bytes or more to anything beyond the headend router i get less than 1% response. If I ping the headend router or other remote sites all is normal, any size is fine.

It was fine a few days ago, not aware of any config changes that might have caused it.

Other remote sites don't have this issue.

Any idea's anyone, got me a bit stumped.

Hi

Can you check out the mtu size specified under the interfaces through which your packet is getting traversed ?

Hope you can verify the config of this spoke with other spokes which are working..
