i suggest set git clone timeout value upto logger value, default 10 minutes. cause error if git repo big enough or networking not good.

here how change default git clone timeout value:

source code management --> git --> add--> additional behaviours -->  advanced clone behaviors --> timeout (in minutes) clone , fetch operations 

you can set 60 mins example.
