I have been using the Elastic Search Cluster for more than a year without any issue, I will be doing regular snapshot backup and deletion of old indices and kept the available disk space on the average for all nodes well below 65%.
Version of Cluster:
"version_id": 5060399,
"version": "5.6.3",
But suddently today i am getting the below error during snapshot
"reason": "IndexShardSnapshotFailedException[Failed to perform snapshot (index files)]; nested: IOException; nested: StorageException[The value for one of the HTTP headers is not in the correct format.
Kindly help me to resolve it
