ERROR 004003: Gateway Timeout. When using Clip

I've developed a toolbox a couple of months ago, prior to 3.5.0 update, that completes a simple task.

It's as simple as importing boundaries from the Living Atlas portal and performing a spatial join then clip.

HUC_06_layer_url = 'https://services.arcgis.com/P3ePLMYs2RVChkJx/arcgis/rest/services/Watershed_Boundary_Dataset_HUC_6s/FeatureServer/0' arcpy.management.MakeFeatureLayer(HUC_06_layer_url, "HUC06") HUC_10_layer_url = 'https://services.arcgis.com/P3ePLMYs2RVChkJx/arcgis/rest/services/Watershed_Boundary_Dataset_HUC_10s/FeatureServer/0' arcpy.management.MakeFeatureLayer(HUC_10_layer_url, "HUC10") arcpy.analysis.SpatialJoin( target_features="HUC06", join_features=installation_A_directory, out_feature_class=HUC06_Out, join_operation="JOIN_ONE_TO_ONE", join_type="KEEP_COMMON", field_mapping=None, match_option="CONTAINS", search_radius=None, distance_field_name="", match_fields=None ) arcpy.analysis.Clip( in_features="HUC10", clip_features=HUC06_Out, out_feature_class=HUC10_Out, cluster_tolerance=None )

This has never happened before when running this tool prior to the 3.5.0 update. I recently applied the update and ran this tool for the first time afterwards. I know the HUC06 and 10 boundaries contain a lot of information and ESRI recommends clipping with a smaller data. I had no issue running the tool with various data (in terms of spatial join). Even performing the task with pairwise clip isn't working. Manually clipping (not my tool, but the clip geoprocessing tool) isn't also working. One resolution I came up with was to set the processing extent (in the environment tab) and limit the X and Y extents. This, however, doesn't always work.

Any idea why this keeps happening?

Thanks in advance!

There is an ArcGIS tool error and warnings page on this error message but it's not terribly helpful - 004003: Gateway Timeout.—ArcGIS Pro | Documentation

All the services are healthy:
ArcGIS Online Health Dashboard
ArcGIS Hub Status
Live Feeds Status

If you do this workflow manually outside of the script, do you still get the same timeout message?

Right, those ArcGIS too error documents weren't that helpful.

And yes, the workflow was attempted with both the script and the geoprocessing tool. Same timeout message shows up. The most prominent solution (highest success rate, but not 100%) is to select the polygons (boundaries) to clip manually by drag and select (mouse) the necessary extents (boundaries).
