Fresh Gitea Installation on Windows Server 2012, but Cannot Push

I’m new to Gitea and I’m testing whether it can be used as an on-premise repo for projects in our organisation.

Version 1.8.1 is setup and running on Windows Server 2012 R2 set up to run as a service with MS SQL Server 2017 being used for the database, and is being run with an Active Directory user account.

It loads, it runs, it looks great.

However, after creating a repo, any attempt at pushing to it, even with a new project with only a, it yields the following:

$ git push -u origin master
Enumerating objects: 6, done.
Counting objects: 100% (6/6), done.
Delta compression using up to 4 threads
Compressing objects: 100% (3/3), done.
Writing objects: 100% (6/6), 499 bytes | 166.00 KiB/s, done.

To http://devsvr:3000/username/something.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'http://devsvr:3000/username/something.git'

Researching this error has revealed that it may be a configuration or script issue. However, I’m not sure how to resolve this issue.

Any help and advice in resolving this issue is most welcome.
