how is these connected direct patch cable ? or you have a provider involved to connect?
GLC-LH-SMD (what kind of patch cable or cable you using to connect both ?)
post below output both the side
show run interface gi x/x
show interface gi x/x
suggest try no negotiation should work

- Make the connection again, and then check the logs on both platforms ,see if you can find anything useful

Connected on one side but "not connected" on the other?
I have seen this before.
Test and make sure the entire length is not broken. The description described is due to one of the fibre pair is broke.
