To fix it you should log it first, because it is impossible to fix an unknown exception.

Try to log the previous exception. E.g.:

} catch (\Exception $e) {
	if ($e->getPrevious()) {
		$this->getLogger()->critical($e->getPrevious());
	}
	$this->getLogger()->critical($e);
	throw new CouldNotSaveException(
		__('An error occurred on the server. Please try to place the order again.'),
		$e
	);
}

It seems magento has problem in payment methods when you logged as customer!
try to checkout as guest and you can see there is no error!!
