Hi @drm.tgam,
Unfortunately, S3 (iglucentral.com is hosted there) outages happen sometimes, which result in this kind of errors. Probably, the best way to avoid it is to set cacheTtl property in resolver configuration to not-very-high value. But cacheTtl is available since R93 (Stream Enrich 0.11.0), so you’ll have to upgrade your stack first. Also Cloudwatch alarms can be useful to get timely notifications - after you get one you can just restart enrich process and it will clean up the cache.
