We will need more informations. Could you look at your Sitecore logs? See what exceptions come out?

According to my compatibility tables here, Coveo for Sitecore 3.0.1055 does not support Sitecore 8.0.150812.

This might be the cause.

Coveo for Sitecore 3.0.1055 supports up to Sitecore 8.0u3.

8.0.150812 is Sitecore 8.0u5. Support for this version has been added in CoveoForSitecore 3.0.1116.

Also, PFA coveo diagnostic page screenshot, which shows that

Coveo for Sitecore 3.0.1055 is compatible with Sitecore 8.0.150812.
