After running nanoroute in Encounter I get the following message
The violations are due to spacing. During route I get the following warning, I don't know if it's a reason for the problem
I have done place and route for other designs using this same library without much problems. I don't think it's a congestion issue, as the density is only 30% or thereabouts.
Where to begin to solve this problem?

The violations are due to spacing. During route I get the following warning, I don't know if it's a reason for the problem
#WARNING (NREX-28) The height of the first routing layer M1 is 0.000000. It should be larger than 0.000000
#WARNING (NREX-29) The metal thickness of routing layer M1 is 0.000000. It should be larger than 0.0. Add this to the technology information for better accuracy.
