packaging succeeded but publishing failed

[PriyaAggarwal1]

I am having trouble in publishing a hosted feature service from ArcMap 10.2 to ArcGIS Portal. When I attempt to publish, I suddenly started getting this error message. Previously it was working fine. 

Log report on server. The warning and severe cases on 2019-09-12 at 09:41 are related to above publishing error.

I have Tested all below methods and still not got any solution:

Restart Publishing tool on server manager

validate Datastore  – Its working perfectly fine

Publish mxd with different names

Tried Publishing layer, feature class, .shp

Tried Publishing Zip file of shp, directly on portal by using add item. 

Windows authentication enable on IIS for server web adaptor

Restart services on task manager

Server drives have sufficient space

Has anyone run into this issue and how can I resolve it?

Thank you for any help or pointers in the right direction!

Are you getting error for any layer or a particular layer? Also if you can share the error message and error number from GP results windows, it would be helpful.

Generic error message in GP Results window, that's a tricky one! Did you try steps given in article that I shared in my second comment?
