ODP_landcover: Network Problebem&Data Access Error

[Evadzi]

Expected behavior

Ingest esacci.LC.5-years.L4.... data using ODP

Actual behavior

Download failed and returns 2 different error types;(a)Network Problem: for ingestion of LC data without regional constraints and (b)Data Access Error: for ingestion of LC with regional Constraints

Steps to reproduce the problem

1. for error(a) ingest esacci.LC.5-years.L4.... without regional constraint
2. *for error(b) ingest esacci.LC.5-years.L4.... with regional constraint( lon -50,50: lat -50, 80)
