After installing the new Nest thermostat. The AC compressor doesn’t turn on all the time. Help

After installation of my new nest thermostat, the ac compressor doesn’t turn on all the time. And if it does, it takes 30 mins to start. Never had this issue with the old regular thermostat.

Post a picture of the original thermostat's wiring if you have it.
