In these cases, I usually remove the Google Account. After waiting a few minutes, and after a reboot of the phone, you can add the Google Account again.

I also saw something recently about Google Sync being affected by malware if you've inadvertently installed one thinking it was another app.<br />
<br />
I couldn't find the exact news article that mentioned it, however these two seem relevant and a good place to check and rule out:<br />

Contacts Sync has stopped on my Android phone.<br />
<br />
I have a LG Q6 Android phone, with only one gmail account linked. Contacts show last sync was a month ago , and stopped ever since. I tried click (Sync Now) several times, also tried to turn off and on the auto-sync now option, but still no success.<br />
Sometimes the sync arrows spins for a seconds, then stops, but the Last Sync date doesn't change.

Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. Android's user interface is based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input. In addition to touchscreen devices, variants of Android are also used on notebooks, game consoles, digital cameras, televisions, automobiles and other electronics. Applications are usually developed in Java programming language using the Android software development kit (SDK), but other development environments are also available, including Delphi, Ruby and Visual Studio (using C++).
