To repo this case:
1. Build a random feature set with more than 300 points in Pro
2. Publish it into Enterprise
3. Run the following code with the url of the published feature
4. You will see the error message

If the number of points is less than 300, the code should work. 

Here is my code:
from arcgis.gis import GIS
from arcgis.features import FeatureLayer, Feature, FeatureSet, FeatureCollection, use_proximity

username=''
password=''
gis = GIS('', username, password, verify_cert=False, set_active=True)

import arcgis.network as network
origins=FeatureLayer('')
destinations=FeatureLayer('')
result1 = network.analysis.generate_origin_destination_cost_matrix(origins=origins, destinations=destinations, gis=gis)

Here is the error message:
