Why is that happening? There are small bugs under the bark that is peeling. Could this be the cause?

Yes, this could definitely be the issue. Treat the tree with neem oil, which will kill the pests and is an effective fungicide too. In addition, you may want to contact an arborist (tree expert) if the tree doesn't show signs of improvement.
